What is the greatest common factor for 78 and 91?

Answer 1

Julian Avila

#13#

You can take the following steps to locate the GCF.

Divide the larger of two numbers by the smaller to find the remainder and quotient.

The GCF is the smaller number if the remainder is zero.

If not, repeat with the remainder and the smaller number.

So for #78# and #91# we proceed as follows:

#91 / 78 = 1# with remainder #13#

#78 / 13 = 6# with remainder #0#

So #13# is the GCF.

To find the greatest common factor (GCF) of 78 and 91, you can use various methods such as prime factorization, listing factors, or using the Euclidean algorithm.

Using prime factorization:

Prime factorize 78: (78 = 2 \times 3 \times 13)
Prime factorize 91: (91 = 7 \times 13)

The common prime factors are 13. Therefore, the GCF of 78 and 91 is 13.
