If the number is odd, that's the answer.
If the number is even, write down all the factors and choose the largest one that is odd.
No. Odd numbers only have odd factors. They could not have an even factor in common.
A perfect square has an odd number of factors.
3 or 7
No. 255 is an odd number.
Because odd numbers don't have any even factors so they can't have one in common.
All nonzero numbers have factors. Some factors are odd numbers. The largest of these would be the greatest odd factor. Of course, the greatest odd factor of any odd number is the number itself.
All nonzero numbers have factors. Some factors are odd numbers. 3 is an odd factor of 12.
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 6th highest odd number is 11.
5 is an odd number and is a factor of 100
A square number has an odd number of factors, but a number with an odd number of factor pairs is nothing special.
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.
The parity (odd or even) of a number has no relevance in reducing fractions. What is required is to find the highest common factor between the numerator and denominator. Clearly, if the numerator and denominator are bot even then 2 is a common factor and so it must be possible to reduce the fraction. The highest common factor or even a common factor may not be so obvious when both numerator and denominator are odd.For example, 21/91 = (3*7)/(13*7) = 3/13
An odd number can't have 12 as a factor. 528 does have 12 as a factor.
Yes. An even number is defined as being evenly divisible by 2 (no fractional answers, only integers). If an odd number has an even factor, then because of the above definition, this odd number must have a factor of 2. But you will be hard pressed to find an odd number that is a multiple of 2, because that is already the definition of an even number. So, odd numbers cannot have even factors and thus odd numbers always have odd factors.
