Does odd number have any common factor as even numbers have 2?

Now if you take away 2 from the previous statement and replace it with any other number (say three), then you could have your own set of definitions, like any number divisible by three is a triplet and all other numbers are say, non-triplet. read more

Yes all odd numbers and all positive natural numbers have 1 as their ‘trivial' factor. But none other than that. If you think about it a little, you would realise it too. read more

All even numbers are evenly divisible by two - hence the terminology even. All even numbers, when written in base ten, end with the digit [math]0, 2, 4, 6[/math] or [math]8[/math]. All even numbers, when written in base two (also known as binary), end with the digit [math]0[/math]. read more

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. read more
