What is the greatest common factor of 42 and 55?
Answer:The greatest common factor of 42 and 55 is 1.The common factors of 42 and 55 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: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 55 are 1, 5, 11, and 55.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 42 are 2, 3, and 7.The prime factors of 55 are 5 and 11.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
What is a common prime factor?
All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
What is the greatest common factor of 42?
There is not a greatest common factor of 42 because there cannot be a greatest 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. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The prime factors of 42 are 2, 3, and 7. Examples: The greatest common factor of 36 and 42 is 6. The greatest common factor of 42 and 91 is 7. The greatest common factor of 42 and 375 is 3.
What numbers have only one prime factor?
Prime numbers.
How do you express the prime numbers in factor tree method?
Since prime numbers only have one prime factor (themselves), factor trees are unnecessary.
What is a prime number factor of 42 less than 10 factor of 70?
2 and 7 are prime numbers less than 10 that are factors of 42 and 70.
What is the largest prime factor of 42?

What is the greatest common factor of 23 and 42?
Since 23 is a prime number, its only factors are 1 and itself. Since 42 is not divisible by 23, the greatest common factor is 1. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 23 are 1 and 23. 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 factor of 23 is 23. The prime factors of 42 are 2, 3, and 7. There are no prime factors in common, so the numbers are relatively prime, meaning the greatest common factor is 1.

What is the prime number's of 42?
The prime numbers (factors) of 42 are: 2,3,7
What is the greatest common factor of 25 and 42?
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.
What are the common factors of 42 and 23?
To work this out, you first have to split the numbers down into their prime factors: 42 = 2x3x7 23 = 23 There are no common prime factors. This means that the only common factor of 42 and 23 is 1.
