They are: 90, 45, 30, 18, 15, 10, 9, 6, 5, 3, 2, 1. These are all the factors of 90, and every entry in the list can divide 90 without rest (modulo 0). That’s why the terms factors and divisors of 90 can be used interchangeably.

As is the case for any natural number greater than zero, the number itself, here 90, as well as 1 are factors and divisors of 90.
