Why Do We Have Prime Numbers?

Prime numbers are like the most basic building blocks of math. Imagine you have a bunch of LEGO bricks, prime numbers are the ones that can't be broken down into smaller LEGO bricks. For example, 2, 3, and 5 are all prime because they only have two factors: 1 and themselves. But 6 isn’t prime because it can be divided by 2 or 3.
