Answer 1

hope it helps u. ....

Step-by-step explanation:

Example 1: Find out the prime factorisation of 30.

First we will see whether the given number is divisible by a least prime number.

Yes, it is, because the digit at its ones place is 0.

30 = 2 × 15

We have, 15 = 3 × 5

Prime-factorisation

So, the factors of 30 are

∴ 30 = 2 × 3 × 5

2, 3, and 5 are prime factors of 30
