Question

Find the smallest natural number that we need to divide 243 with to make it a perfect square

Answer 1

Let us prime factorise 243 first.

243 = 3×3×3×3×3

We can see that there are 5 3s in its prime factorisation.

We need to arrange the prime factors into pairs.

We observe that 2 such pairs can be formed and one 3 is left behind.

So the smallest number by which 243 needs to be divided is 3.

243÷3 = 81 ( 9² )
