Answer:

Six numbers have perfect square factors

Explanation:

The numbers with perfect square factors are those numbers that have perfect squares as one of the numbers that can divide them.

They include:

4 = 2 * 2

16 = 4 * 4

36 = 6 * 6

49 = 7 * 7

64 = 8 * 8

81 = 9* 9

These numbers above have perfect square factors because they are formed from integers that multiply themselves.
