All integers must be able to be divided by another integers (even if its one)
A prime number is an integer whose only divisors are one and itself
All $ x \in \mathbb{R} $ can be written as a product of prime numbers
$ x = P_{1}^R + P_{2}^R + P_{3}^R … P_{n}^R $
The Greatest Common Divisor (GCD) is the largest number that can be evenly divide into both numbers. For example, the gcd(36, 24) = 12
The Lowest Common Multiple (LCD) is the lowest number that is a multiple of both numbers. For example, the lcm(36, 24) = 72
