Any of the prime numbers that can be multiplied to give the original number is known as prime factorisation.

1. The prime factors of 225 are 5 × 5 × 3 × 3. This can also be written as is 5²×3²Answer.

2. The prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5 = 160. This can be written as 2⁵×5 Answer

3. The prime factors of 90 are 3×3×2×5= 90. This can be written as

3²×2×5 (Answer).

4. The prime factors are: 2 x 2 x 2 x 3 x 3 x 3 x 5.

This, can be written as 2³×3³×5 which is the answer.

We got it by getting LCM.
