Question

Find the missing digits in the step diagram factorization shown below.

• A. A = 2; B = 72; C = 3; D = 9
• B. A = 2; B = 92; C = 3; D = 9
• C. A = 2; B = 108; C = 2; D = 9
• D. A = 1; B = 72; C = 3; D = 9

Answer 1

The correct option is A A = 2; B = 72; C = 3; D = 9

The given step diagram represents the prime factorization of 144.

By finding the prime factors of 144 using step diagram method, we get:

A = 2; B = 72; C = 3; D = 9
