A square number has an odd number of factors, but a number with an odd number of factor pairs is nothing special.
L
2 cannot be a factor of an odd number, 2 must be a factor of an even number.
3 is a factor of 24 that is an odd number bigger than 1
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.
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.
L
No odd number has an even factor.
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.
5 is an odd number and is a factor of 100
Odd.
One of the factor pairs for a square number will be the same number twice. When you list the factors, you only need to write that number once. That will leave you with an odd number of factors.
The factor pairs of 429 (all odd numbers) are (429,1)(143,3)(39,11)(33,13)
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.
Odd.
