Question

Which one of the following shows the prime factorization of the number 24?

• A. 6 $\times$ 4
• B. 2 $\times$ 2 $\times$ 2 $\times$ 3
• C. 12 $\times$ 2
• D. 3 $\times$ 4 $\times$ 2

Answer 1

The correct option is B 2 $\times$ 2 $\times$ 2 $\times$ 3

The factors of a number which are prime are called prime factors.

A factorization in which every factor is prime is called prime factorization of the number.

24 can be written as:

24
= 2 $\times$ 12
= 2 $\times$ 2 $\times$ 6
= 2 $\times$ 2 $\times$ 2 $\times$ 3

So, prime factorization of 24:
2 $\times$ 2 $\times$ 2 $\times$ 3.
