The greatest common factor of 25 and 42 is 1 because it is the only common factor.
There is neither a greatest common factor nor common factors of a single number, such as 25, 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.The factors of 25 are 1, 5, and 25.Examples:The common factors of 13 and 25 are only 1; the greatest common factor is 1.The common factors of 23 and 25 are only 1; the greatest common factor is 1.The common factors of 25 and 30 are 1 and 5; the greatest common factor is 5.The common factors of 25 and 42 are only 1; the greatest common factor is 1.The common factors of 25 and 50 are 1, 5, and 25; the greatest common factor is 25.
The greatest common factor of 42 depends upon the other numbers with which 42 has COMMON factors. However, the greatest common factor HAS to be one of the factors of 42 which are: 1, 2, 3, 6, 7, 14, 21, 42.
There is neither a greatest common factor nor common factors of a single number, such as 25, 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. The factors of 25 are 1, 5, and 25. The prime factors of 25 are 5 and 5. Examples: The common factors of 13 and 25 are only 1; the greatest common factor is 1. The common factors of 23 and 25 are only 1; the greatest common factor is 1. The common factors of 25 and 30 are 1 and 5; the greatest common factor is 5. The common factors of 25 and 42 are only 1; the greatest common factor is 1. The common factors of 25 and 50 are 1, 5, and 25; the greatest common factor is 25.
The common factors of 42 are the numbers that can evenly divide 42 without leaving a remainder. The common factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The greatest common factor (GCF) of 42 is the largest number that can divide 42 and another number without leaving a remainder. In this case, the GCF of 42 and any other number would be 42 itself.
The GCF of 42 and 86 is 2. 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 86 are 1, 2, 43, and 86. The common factors are 1 and 2. Therefore, the greatest common factor is 2.
The common factors of 21 and 42 are 3, 7 and 21. The greatest common factor (GCF) is 21.
Answer: 1Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method: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 7 are 1 and 7.The factors of 25 are 1, 5, and 25.The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.
The greatest common factor is 14
The greatest common factor is 14
The Greatest Common Factor = 2
Factors of 28... 1,2,4,7,14,28 Factors of 42... 1,2,3,6,7,14,21,42 GCF = 14
Answer: 1. One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 25 are 1, 5, and 25.The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.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 factors of 25 are 5 and 5.The prime factors of 42 are 2, 3, and 7.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.Another way to approach this is to look at the difference between 25 and 42, which is 17. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference between the numbers. Since 17 is a prime number, the greatest common factor must be either 1 or 17. Neither 25 nor 42 are divisible by 17, so the greatest common factor is 1. This is a useful shortcut if you notice that the difference between the two numbers is a prime number.
