What is the GCF of 94 and 47?

Answer 1

GCF(47, 94) = 47.

Answer 2

47 is a factor of 94: 47*2 = 94.

Suppose you are looking for the GCF of two numbers and that that one of the numbers is a multiple of the other. Then their GCF is always smaller of the two number.

Every number is a factor of itself, so the smaller number is a factor of itself. Also, if the bigger number is its multiple, then it must also be a factor of the bigger number. So it is a common factor.

Now, any number that is bigger than the smaller of the two numbers cannot be its factor. So, the common factor found earlier must be the greatest such number.

Answer 3

Since 47 is a factor of 94, it is automatically the GCF.

Answer 4

47
