Answer 1

Answer:

Correct option is

A

3

We are going to find prime factors of 14283

14283=3×4761

=3×3×4761

=3×3×3×529

=3×3×3×23×23

Now, we are going to make a group of equal number.

=(3×3)×(23×23)×3

By observation, 3 prime factor left out.

So, divide by 3 we get,

14283÷3= (3×3)×(23×23)

=(3×23)×(3×23)

=69×69

=(69)

2

∴ To make perfect square we have to divide 14283 by 3.
