Question

4.) The numbers 792 and 990, written as the products
of their prime factors, are 792 = 23 x 32 11
and 990 = 2 x 32 x 5 x 11. Hence, find the
greatest whole number that will divide both
792 and 990 exactly.

Answer 1

Answer:

198

Step-by-step explanation:

The number 792 can be written as the multiplication of its prime factors as (2×2×2×11×3×3) and the number 990 can be written as the multiplication of its prime factors as (5×2×11×3×3).  

Hence, the common factors of those two numbers are 2, 11, 3, 3.

Therefore, the greatest whole number that will divide both 792 and 990 is (2×11×3×3) =198. (Answer)
