Answer:
1. the prime factors of 18 are 2 × 3 × 3 or we can also write them as 2 × 32, where 2 and 3 both are prime numbers.
2.Since 2 is prime, the prime factorization of 20 is 2 * 2 * 5
3.So, the prime factors of 28 are written as 2 × 2 × 7 or 22 x 7, where 2 and 7 are the prime numbers.
4.32 is 2 x 2 x 2 x 2 x 2.
