Prime numbers are those numbers that have only two factors. 1 and itself.
For example 7 is a prime number because it has only two factors 1 and 7 itself.

Look at the word prime in capital letters. Focus on the last 3 letters
I M E. I looks like 1 so 1 is a factor. And the other two letters are M and E that is me!
So the other factor is me or the number itself!

So the factors of any prime number are hidden in the word PRIME itself!
