Given: A number 2880
To find: The smallest number to be multiplied with 2880 to make it a perfect square
Solution: Using Prime factorization, we get
2880 = 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3 × 5
We can see that prime factorization of 2880 consists three pairs of 2 and one pair of 3, while 5 couldn't make any pair.
It is clear that in order to get a perfect square, one more 5 is required.
i.e., 2880 × 5 = 14400 (which is a perfect square).
Hence, the smallest number to be multiplied with 2880 to make it a perfect square is 5.
