Any of their multiples
6 numbers can go into 20; they are 1, 2, 4, 5, 10 and 20.

The counting numbers from 1 to 20 are called natural numbers. There are larger sets that include the numbers from 1 to 20, but have other members as well. For example, the integers contain 1 through 20, but also all numbers 21, 22, 23, ... The set of real numbers includes all numbers on the number line, which includes 0 and negative numbers and irrational numbers like pi, but also includes 1 through 20. Etc.
