What is a Product of primes?

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

7x5=35

13x11=143

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.
