The numbers that are n times 15 is known as multiple of 15. The numbers are 15, 30, 45, 60, 75, 90, 105, 120, 135, 150,..............
In the given question we have to find what is 15 a multiple of.
The numbers that are n times 15, where n is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and so forth, are considered multiples of 15. Therefore, multiples are essentially any integer multiplied by n, where n is a list of all natural numbers. Thus, the multiples of 15 have the form of 15n, as in:
15×1, 15×2 ,15×3 ,15×4, 15×5, 15×6, 15×7, 15×8, 15×9, 15×10,....................
15, 30, 45, 60, 75, 90, 105, 120, 135, 150,................................
