Question

Which of the following shows the prime factorization of 20? A. 2 × 2 × 5 B. 4 × 10 C. 4 × 5 D. 2 × 10

Answer 1

Prime factors are factors of a number that are themselves prime numbers. Prime factorization is when we break a number down into factors that are only prime numbers.

Therefore, the prime factorization of 20 can be done as,

$20=2\times2\times5$

Thus, the first option is correct.
