Numbers without factors are PRIME Numbers.

Taking the first ten numbers.

1,2,3,4,5,6,7,8,9,10.

The prime numbers are 2,3,5,7, they have no factors.

4,6,8,9,10. Are not prime numbers as they have factors.

4 has a factor of '2'

6 has factors of '2 & 3'.

8 has factors of' 2 & 4'. or' 2,2,2.'

9 has factors of '3,3',

10 has factors of '2 5.'

'1' is unique
