Answer:
GCF of 112 and 42 = 14
Step-by-step explanation:
One way is to find the prime factors of each of the numbers and pick out the common ones.
For example
Find the GCF of 112 and 42:-
112 = 2 * 2 * 2 * 2 * 7
42 = 2 * 3 * 7
There are a pair of 2's and a pair of 7's in both lists so the
GCF = 2*7 = 14.
