If your number must be an integer, you would need to solve for x:

60x=p2,{x,p}∈Z60x=p2,{x,p}∈Z

Note that 60=22⋅3⋅5.60=22⋅3⋅5.The prime factorization of a perfect square can be recognized by all EXPONENTS having even parity. In this case, 2 already does but 3 and 5 don’t; multiplying by 15 (3×5)15 (3×5) PRODUCES 900=302=22⋅32⋅52.900=302=22⋅32⋅52.

If you consider 0^2 as a perfect square, then the lowest number that has to he MULTIPLIED to 60 to make a perfect square is zero.

If you want the perfect square of a positive integer and can use fractions, you could MULTIPLY 60 by 1/60 to GET 1^2 or 1.

Lastly, if you want a perfect square that is greater than 60 AND where you multiply by an integer to get to that perfect square, we can start by prime factoring 60:

60 = 2^2 x 3 x 5

If you want a perfect square, you want every factor of that number to have an even power. Thus, you multiply 60 by 15 (3 x 5) to get all the powers even. This equals 900 or 30^2.
