Question

Find the smallest number by which 240 must be multiplied so that the product is a perfect square. *

Answer 1

Answer:

15

Step-by-step explanation:

$240 = 2 \times 2 \times 2 \times 2 \times 3 \times 5 \\ = {2}^{4} \times 15$

Here, 15 is not a square number so, 240 should be multiplied by 15 to make 240 as perfect square.

240* 15 = 3600
