What is a Product of primes?

A prime number is one that can't be evenly divided by anything except 1 and itself.
The smallest primes are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37 .  Every number
missing from this list can be evenly divided by something besides 1 and itself.
For example: 18 is missing from the list.  It can be divided by 1, 2, 3, 6, 9, and 18 .
So 18 is not a prime number.

Every whole number that's NOT a prime number is the product of prime numbers.
For example:
18 is the product of [ 2 x 3 x 3 ] .
32 is the product of [ 2 x 2 x 2 x 2 x 2 ]
33 is the product of [ 3 x 11 ] .

' 2 ' is the only even prime number.  Every other even number can be divided by 2 ,
so all the rest of the primes bigger than 2 are odd numbers.

There are many other interesting features of prime numbers.

When u multiply two prime numbers together, you always end up with an odd number.

7x5=35

13x11=143
