Question

Find the least number by which 1392 should be multiplied to make it a perfect square​

Answer 1

Answer:

$\huge\orange{87}$

Step-by-step explanation:

Prime Factorisation:

$1392 = 2 \times 2 \times 2 \times 2 \times 3 \times 29$

We can see that there 2 can be made into 2 pairs of Numbers ,

But , we are not able to make similar pairs for 3 and 29.

$> > \sqrt{1392}$

$> > \sqrt{2 \times 2 \times 2 \times 2 \times 3 \times 29}$

$> > 2 \times 2 \sqrt{3 \times 29}$

$> > 4 \sqrt{3 \times 29}$

So, 1392 should be multiplied with (3 x 29) ,ie, $\orange{87}$ to make it a Perfect Square.
