Prime Number
A positive integer, p > 1, that can only be divided by 1 or itself (p).
The first few primes are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, ...
See the Sieve of Eratosthenes

The Fundamental Theorem of Arithmetic (or Unique-Prime-Factorization Theorem)
Any integer greater than 1 can be written as a unique product of prime numbers. 3:2 are prime numbers that are divisible by one or itself. They can't be divided up or broken down into smaller integer whole numbers.

Greatest Common Divisor, GCD(a,b)
Examples: GCD(3,7) = 1, GCD(24,60) = 1, GCD(24,120) = 24
Using GCD(24,120) a = 3*2*2*2 = 24, b = 5*3*2*2*2 = 120. The overlap is 3*2*2*2 = 24

120Hz 1-1-1-1-1-2-2-2-2-2-3-3-3-3-3-
