What is the greatest common factor of 20 and 31?
The greatest or highest common factor is 1
What is the greatest common factor of 13 and 20?
The Greatest Common Factor (GCF) of 13 and 20 is: 1
What is the greatest common factor of 20 21 and 25?
The greatest common factor of 20, 21, and 25 is 1. Although 20 and 25 can be divisible by 5, 21 can not. Therefore, the only common factor between these three numbers is 1 and it's the greatest one as well.
What is the greatest common factor of 51 and 20?
Greatest common factor of 20 & 51 is 1. Factors of 20 are 1, 2, 4, 5, 10 & 20. Factors of 51 are 1, 3, 17 & 51. The only common factor is 1, so GCF is 1. Alternate method: Prime factorization of 20 = 2x2x5 Prime factorization of 51 = 3x17 From the prime factorizations it is clear that 1 is the GCF of 20 and 51.
What is the greatest common factor of 19 and 20?
The GCF of 19 and 20 is 1.
What is the greatest common factor of 20 and 31?
The greatest or highest common factor is 1
What is the Greatest Common Factor of 4 and 7 and 20?

What is the greatest common factor of 13 and 20?
The Greatest Common Factor (GCF) of 13 and 20 is: 1
What is the greatest common factor of 17 and 18 and 20?
Since 17 is a prime number, the greatest common factor of 17, 18, and 20 is 1.
What are the common factors and greatest common factor of 20?
There is neither a greatest common factor nor common factors of a single number, such as 20, 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 20 are 1, 2, 4, 5, 10, and 20. The prime factors of 20 are 2, 2, and 5. Examples: The common factors of 20 and 70 are 1, 2, 5, and 10; the greatest common factor is 10. The common factors of 20 and 32 are 1, 2, and 4; the greatest common factor is 4. The common factors of 20 and 140 are 1, 2, 4, 5, 10, and 20; the greatest common factor is 20.

What is the greatest common factor of 20 8 and 5?
The greatest common factor of 20, 8, and 5 is 1. (5 only has two factors: 1 and 5, and 5 is not a factor of 8.)
What is the greatest common factor of 20 21 and 25?
The greatest common factor of 20, 21, and 25 is 1. Although 20 and 25 can be divisible by 5, 21 can not. Therefore, the only common factor between these three numbers is 1 and it's the greatest one as well.
What is the greatest common factor of 51 and 20?
Greatest common factor of 20 & 51 is 1. Factors of 20 are 1, 2, 4, 5, 10 & 20. Factors of 51 are 1, 3, 17 & 51. The only common factor is 1, so GCF is 1. Alternate method: Prime factorization of 20 = 2x2x5 Prime factorization of 51 = 3x17 From the prime factorizations it is clear that 1 is the GCF of 20 and 51.
