Question

Find the least number by which 2940 must be multiplied byto get a perfect square

Answer 1

Heya !!!


This is your answer.....

Given :- 2940.

2940= 2×2×3×5×7×7

We can see that 2 and 7 forms a pair, but 3 and 5 are left unpaired.

So, if we multiply it by 3 and 5. The pair will get completed and it will become a perfect square.
So,
2940×3×5 = 2×2×3×3×5×5×7×7

It is a perfect square.

Hence, the number by which 2940 should be multiplied to get a perfect square is 3×5=15.

Hope it helps
