A square number has an odd number of factors, but a number with an odd number of factor pairs is nothing special.

2 cannot be a factor of an odd number, 2 must be a factor of an even number.
You cannot do this, because you're taking odd numbers: if you add two odd numbers together, you will get an even number. Take the odd numbers in pairs, so you'll have 3 pairs plus an extra odd number. The 3 pairs make 3 even numbers. You can add up any number of even numbers and get an even number, so you will have an even + odd, which is odd. 30 is an even number, but your result will be odd, no matter what 7 odd numbers you choose.
3 is a factor of 24 that is an odd number bigger than 1
2 is a factor of every even number. Adding or subtracting one from an even number leaves an odd number. Since even and odd numbers alternate, 2 will be a factor of every other number.

Factors can be listed as factor pairs. With square numbers, one of those pairs will be the same number twice. When written as a list, only one of them will be used, leaving an odd number of factors.
I would call an odd number factor a factor that is an odd number. I would call a number with an odd number of factors a perfect square.
The factor pairs of 429 (all odd numbers) are (429,1)(143,3)(39,11)(33,13)
5 is an odd number and is a factor of 100
Odd.
All odd numbers have odd factors.
An odd factor is a number that cannot be divided by 2. if it can be divided by 2 it is an even factor or even number.
25 is an odd factor of 100.
An odd number can't have 12 as a factor. 528 does have 12 as a factor.
