Question

Prime factorization of 18 would be

• A. $6\times 3$
• B. $3\times 2\times 3$
• C. $9\times 2$

Answer 1

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

$\underset{–}{Concept}$:
Prime factorization of a number means representing number as a product of its prime factors.

$\underset{–}{Method}$:
18 can be factorised as:

$18=9\times 2=3\times 3\times 2$

$18=3\times 3\times 2$ would be the final Prime Factorization of 18 since it cannot be further reduced to any prime number.
