The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers.
eg Number A = 18, Prime factors = 2*3*3
Number B = 24, Prime factors = 2*2*2*3
The Prime factors that A and B have in common are 2 and 3
Multiply them together = 6
6= the GCF of 18 and 24

What is the largest shared factor of two numbers called?
That's the greatest common factor, or GCF.
What is a factor that two or more numbers share called?
That's the greatest common factor, or GCF.
What is the greatest common factor of 34?
There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
What does it mean to share a common factor?
A common factor of several numbers is a number that can divide evenly into each one of them. '10' is a common factor of 20 and 30. '5' is a common factor of 10 and 15. '3' is a common factor of 6, 9, and 12. '2' is a common factor of all even numbers. '1' is a common factor of all whole numbers.
What is the greatest common factor of 62 93 and 31?
The greatest common factor (GCF) of 62, 93, and 31 is 31. To find the GCF, you need to determine the factors of each number and identify the largest factor that is common to all three numbers. In this case, 31 is the only factor that all three numbers share, making it the greatest common factor.
