Step-by-Step: How to List the Multiples of 805

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 805 by each integer from 1 to k:

1. 805 × 1 = 805
2. 805 × 2 = 1610
3. 805 × 3 = 2415
4. …continue up to 805 × 20 = 16100.
5. Sum of these 20 multiples: 805 × (1+2+…+20) = 805 × 210 = 169050.

Shortcut: the sum of the first 20 multiples of 805 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 M_n = {0, 1·n, 2·n, 3·n, …}. For example: M₈₀₅ = {0, 805, 1610, 2415, 3220, …}.
