PRIME NUMBERS
Prime numbers under 50 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. Prime numbers are used to find common denominators.

All natural numbers can be broke down into prime factors. These have been colored so we can learn or memorize the prime numbers under a hundred. This will usually hand our problems.
