The same number is multiplied with itself to form a perfect square i.e. a perfect square has real and repeated equal numbers as factors.
If you mean 'prime' factors, then an odd number of them CAN'T produce a perfect square. Consider 3 factors ... A, B, and C. If their product were a perfect square, then AxB=C, which can't be true if C is a prime number. For non-prime factors, an odd number of them may or may not be a perfect square: Three factors = not a square: 2 x 3 x 5 = 30. Three factors = a square: 2 x 3 x 6 = 36.
the only perfect square factor of 90 is 9
A perfect square

All numbers have factors. Some factors are perfect squares. We call these perfect square factors. 9 is a perfect square factor of 27.
The perfect square factor of 50 is 25 and the perfect square factor for 90 is 9. The perfect square factors for 50x90 25x9. Of course we also have the other factors of 2 and 2x5.
A perfect square has an odd number of factors.
The same number is multiplied with itself to form a perfect square i.e. a perfect square has real and repeated equal numbers as factors.
A perfect square has an odd number of factors. Factors of numbers always come in pairs -- except for perfect squares. Since the square root of a perfect square is listed only once on the list of factors, it results in a list with an odd number of factors.
If you mean 'prime' factors, then an odd number of them CAN'T produce a perfect square. Consider 3 factors ... A, B, and C. If their product were a perfect square, then AxB=C, which can't be true if C is a prime number.
