The answer is 230.

STEP 1-First do prime factorization of 3610 STEP 2-Make pairs for each (2 numbers of the same value)STEP 3-The digit which is left alone is the least number to be multiplied by 3601 to make it a perfect square.

Yes.... look at the number 20. It's a composite and it does have a square root.

3600 is the smallest perfect square divisible by 8,9 and 10. Work out the prime factorisations for each of the numbers 8, 9, 10: 8 = 23 9 = 32 10 = 2 x 5 So the perfect square must be a multiple of the lcm of 8, 9 & 10 = 23 x 32 x 5 to be divisible by all three numbers. All perfect squares have even powers for all their primes (in their prime factorisation), so to make all the powers even the smallest multiplier of this is 2 x 5, giving 24 x 32 x 52 = 3600.
