Multiples

Pick a value to view its full reference table.

Multiples of 1 are what you get when you multiply 1 by whole numbers. Common multiples of two numbers lead to the LCM.

Multiples are skip-counting made systematic: n, 2n, 3n marching outward forever. They share their last-digit rhythm with the multiplication table, pair-sum to 11n in batches of ten, and the common multiples of any two numbers are exactly the multiples of their LCM — the smallest meeting point worth finding first. Every page in this section lists the first twelve multiples and names the first shared multiple with 2 and with 3. Twelve is the classic cutoff for both drills and division checks.

All 20 multiples pages include a full data table, a worked explanation, and related calculators. Start withnumber 1or jump straight to the value you need below.
