Answer 1

Answer:

The instructions to find the GCF of 112, 210 and 252 are the next:

1. Decompose all numbers into prime factors

1122562282142771 21021053355771 25221262633213771

2. Write all numbers as the product of its prime factors

Prime factors of 112=24 . 7Prime factors of 210=2 . 3 . 5 . 7Prime factors of 252=22 . 32 . 7

3. Choose the common prime factors with the lowest exponent

Common prime factors: 2 , 7

Common prime factors with the lowest exponent: 21, 71

4. Calculate the Greatest Common Factor or GCF

Remember, to find the GCF of several numbers you must multiply the common prime factors with the lowest exponent.

GCF = 21. 71 = 14
