Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF
This is what I would write: "What is the GCF of 32 and 64?"
There is always a GCF, even if it's only 1.
The prime factorization of 9 is 32 You need at least two numbers to find a GCF.
9 and 18
Find the GCF of the numerator and the denominator and divide them both by it. If the GCf is 1, the fraction is in its simplest form.
It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! There is, therefore no GCF and so answer to the question.
Find the GCF of the numerator and the denominator and divide them both by it. If the GCF is 1, the fraction is in its simplest form.
Find the GCF of the numerator and denominator and divide them both by it. If the GCF is 1, the fraction is in its simplest form.
you have to find the GCF of the two numbers
Any non-zero whole number can be a GCF under the right circumstances. That makes the answer infinite and difficult to write down.
To find the gcf of 48 and 88, first write both the numbers in terms of their prime factors48=2x2x2x2x388=2x2x2x11Now find the common among them=2x2x2=8 = GCF
The GCF of those numbers is 1. You may have meant to write 78, 91 and 156. In that case, the GCF is 13.
