To determine the least number that must be multiplied to 21168 to make it a perfect square, we first find its prime factorization: (21168 = 2^4 \times 3^1 \times 11^1). For a number to be a perfect square, all the exponents in its prime factorization must be even. Here, the exponent of 3 and 11 are odd, so we need at least one more factor of each. Thus, we multiply by (3^1 \times 11^1 = 33). Therefore, the least number that must be multiplied to 21168 to make it a perfect square is 33.

It is: 8 because 8*217800 = 1742400 which is a square number

As the question is phrased, the answer is 1/120 which would give the product 1: a perfect square. But the "correct" answer is, presumably, 30.
64: 1, 2, 4, 8, 16, 32, 64Tip: To find the number, consider that if there are an odd number of factors, the number must be a perfect square, because a perfect square has one factor that is multiplied by itself. 64: 1, 2, 4, 8, 16, 32, 64Tip: To find the number, consider that if there are an odd number of factors, the number must be a perfect square, because a perfect square has one factor that is multiplied by itself.

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.
