What kind of number has an odd number of factors

i.e odd number only has the odd number of factors.

For example, the factor of 1 is 1[ which is odd number]

the factor of 3 are 1 & 3 [which are odd number]

the factor of 15 are 1,3, 5 & 15 [which are odd number]

Note: Remember! even number has both odd and even number of factors.

It is so because 1 is the factor of all numbers & it is an odd number.

Hope this has helped you. Now share the idea with your friends too.
