Step-by-Step: How to List the Multiples of 1815

A multiple of n is the result of multiplying n by any natural number (1, 2, 3, ...). To list the first k multiples, just multiply 1815 by each integer from 1 to k:

  1. 1815 × 1 = 1815
  2. 1815 × 2 = 3630
  3. 1815 × 3 = 5445
  4. …continue up to 1815 × 20 = 36300.
  5. Sum of these 20 multiples: 1815 × (1+2+…+20) = 1815 × 210 = 381150.

Shortcut: the sum of the first 20 multiples of 1815 always equals 210n, since 1+2+…+20 = 210.

Facts About Multiples

  • Any number is a multiple of itself (n × 1 = n).
  • Any number is a multiple of 1 (1 × n = n).
  • Zero is a multiple of any number (0 × n = 0).
  • The set of multiples of a number is infinite — every natural-number multiplier produces another multiple.
  • If two numbers a and b are multiplied, the product a × b is a common multiple of both (but not necessarily the least common multiple — LCM).

The set of multiples of n can be represented as Mn = {0, 1·n, 2·n, 3·n, …}. For example: M1815 = {0, 1815, 3630, 5445, 7260, …}.
