Which Numbers that six factors between 1 and a 100?

Answer 1

The numbers with exactly six factors between 1 and 100 are those that are perfect squares. Perfect squares have an odd number of factors because they have one factor that is repeated (the square root of the number). The factors of a number come in pairs, except for perfect squares. In this case, the factors are 1, the square root of the number, and the number itself. Examples of numbers with exactly six factors between 1 and 100 are 4, 9, 25, and 49.
