2352=2×2×2×2×3×7×7

As the prime factor 3 has no pair, 2352 is not a perfect square.

If 3 gets a pair then the number will become perfect square.

So, we multiply 2352 by 3 to get,

2352×3=2×2×2×2×3×3×7×7

2352×3=7056 is a perfect square.

Thus, the required smallest multiple of 2352 is 7056 which is a perfect square.

7056=2×2×3×7=84
