Colossally abundant number
In math, a colossally abundant number (also written as CA) is a type of natural number that has to follow a special set of rules. CAs usually have a lot of divisors. To figure out whether or not a number is a CA, however, it has to follow an equation. For a number to be colossally abundant, ε has to be greater than 0. k a number greater than 1 and σ is the sum of every divisor that the number has.
