What is the greatest common factor of 126 and 70?
Answer:The greatest common factor of 70 and 126 is 14.The common factors of 70 and 126 are 1, 2, 7, and 14.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70.The factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126.The common factors are 1, 2, 7, and 14. Therefore, the greatest common factor is 14.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 70 are 2, 5, and 7.The prime factors of 126 are 2, 3, 3, and 7.The prime factors in common are 2 and 7, so the greatest common factor is 2 x 7 = 14.It is: 14
What are the common factor of 42 and 63?
A factor is a divisor - a number that will evenly divide into another number. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 63 are 1, 3, 7, 9, 21, and 63. The common factors are 1, 3, 7, and 21.
What are the Common factors of 24 and 25?
21 and 25 share no common factors aside from 1.
What is the highest common factor of a number?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. The largest of these is known as the greatest common factor, or GCF.The factors of 30 are:1, 2, 3, 5, 6, 10, 15, 30The factors of 42 are:1, 2, 3, 6, 7, 14, 21, 42The common factors are:1, 2, 3, 6The Greatest Common Factor:GCF = 6
What does common prime factors mean?
When two or more numbers have one or more of the same primes as factors, those prime factors are called common prime factors. For example, the prime factors of 6 are 2 and 3, and the prime factors of 21 are 3 and 7, so 3 is a common prime factor of 6 and 21.
Which pair of numbers has 3 and 7 as common factors?
21 and 42
What are the common factors of 21 and 35?
The common factors are 1 and 7.
What are the Greatest common factor of 63 and 147?
Answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 147, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. Examples: The common factors of 14 and 147 are 1 and 7; the greatest common factor is 7. The common factors of 147 and 171 are 1 and 3; the greatest common factor is 3.
What are the common factors of 8 and 7?
Factors that are the same for two or more numbers are their common factors.What numbers are factors of both 7 and 8?Factors of 7 are 1, and 7.Factors of 8 are 1, 2, 4, and 8.Common factors are the numbers that are in both lists.So, 1 is the common factor of 7 and 8.
What are the common factors of 3 and 7?
A factor is a divisor - a number that will evenly divide into another number. One way to determine the common factors (and greatest common factor) is to find all the factors of the numbers and compare them. The factors of 3 are 1 and 3. The factors of 7 are 1 and 7. The only common factor is 1. In a case like this, since both numbers are prime, there will only be one common factor - the number 1.
What are the common factors of 12 and 21?
The common factors of 12 and 21 are 1 and 3. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. This means that the greatest common factor is 3. The numbers are 1 and 3
What are the common factors of 126?
There are no common factors of 126 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126. The prime factors of 126 are 2, 3, 3, and 7. Examples: The common factors of 4 and 126 are 1 and 2. The common factors of 36 and 126 are 1, 2, 3, 6, 9, and 18. The common factors of 49 and 126 are 1 and 7. The common factors of 12, 30, and 126 are 1, 2, 3, and 6.

What prime factors do the numbers 126 and 147 have in common?
They are 3 and 7
What is the greatest common factor of 39 and 42?
Answer:The common factors of 39 and 42 are 1 and 3.The greatest common factor of 39 and 42 is 3.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 39 are 1, 3, 13, and 39.The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The common factors are 1 and 3. Therefore, the greatest common factor is 3.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. To then obtain the common factors, list all the factors of the greatest common factor.The prime factors of 39 are 3 and 13.The prime factors of 42 are 2, 3, and 7.The only prime factor in common is 3, so the greatest common factor is 3. The factors of 3 are 1 and 3, which are the common factors.
Common factors of 42 and 28?
Factors are numbers you can multiply together to get another number. Common factors are the factors two or more numbers have in common. 28: 1, 2, 4, 7, 14, 28 42: 1, 2, 3, 6, 7, 14, 21, 42 The common factors of 28 and 42 are 1, 2, 7 and 14.
What is the greatest common factor of 7 and 9?
Answer:The greatest common factor of 7 and 9 is 1.The common factors of 7 and 9 are only 1.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:The greatest common factor (gcf) of 7 and 9 is 1. This is because 7 is a prime number. Whenever one number is prime, if it is not a factor of the other number, the greatest common factor is 1.Another way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 7 are 1 and 7.The factors of 9 are 1, 3, and 9.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factor of 7 is 7.The prime factors of 9 are 3 and 3.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.1 because factors of 7 are 1,7 and factors of 9 are 1,9,3 and the largest factor they have in common is 1.The GCF is 1.
