Answer 2

Answer:

1.Greatest common factor (GCF) of 7 and 18 is 1. We will now calculate the prime factors of 7 and 18, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 7 and 18.

2.The greatest common factor of 12, 30 and 54 is 6.

3.7

7The GCF of 14 and 35 is 7.
