What is a multiple of 15?

A multiple of 15 is any number that can be evenly divided by 15 without leaving a remainder. Some examples of multiples of 15 include:

• 15: It is the smallest multiple of 15 since 15 divided by 15 equals 1.
• 30: It is also a multiple of 15 since 30 divided by 15 equals 2.
• 45: It is a multiple since 45 divided by 15 equals 3.
• 60: It is divisible by 15 since 60 divided by 15 equals 4.

Multiples of 15 continue indefinitely, and they are always found by multiplying 15 by a whole number. Hence, the sequence of multiples of 15 would look like this: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, and so on.

Moreover, multiples of 15 have some interesting characteristics. For example:

• All multiples of 15 are also multiples of 5 and 3 since 15 is divisible by both 5 and 3.
• The sum of the digits of every multiple of 15 will always be either 6 or 9.
• With two consecutive multiples of 15 (such as 45 and 60), the number halfway between them (52.5) is also divisible by 15.
