How do you find the GCF of 42 and 56?

Answer 1

Aurora Arias

The GCF of #42# and #56# is #14#.

The following is one way to determine the GCF of two numbers:

To find the remainder and quotient, divide the larger number by the smaller one.

If the remainder is #0# then the smaller number is the GCF.

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

Thus, in our instance:

#56 / 42 = 1" "# with remainder #14#

#42 / 14 = 3" "# with remainder #0#

So the GCF of #56# and #42# is #14#

To find the Greatest Common Factor (GCF) of 42 and 56, you can use the method of prime factorization.

Step 1: Find the prime factorization of each number:

Prime factorization of 42: 2 × 3 × 7
Prime factorization of 56: 2 × 2 × 2 × 7

Step 2: Identify the common prime factors: The common prime factors are 2 and 7.

Step 3: Multiply the common prime factors together: 2 × 7 = 14

Therefore, the GCF of 42 and 56 is 14.
