Random Multiple Of Generator
Generates a random multiple of a base number you choose (multiplier between 2 and 100) — useful for times-table practice or placeholder data.
What this generator does
Picks a random multiple of a number you choose, for maths practice on times tables and for generating values that must land on a step boundary.
How to use this tool
- Set your base number.
- Press generate for a random multiple of it.
Worked examples
- Example shape
- Multiples of 7: 14, 35, 56, 91 …
Common use cases
- Times-table and multiples practice
- Quick maths puzzles
- Placeholder numeric data
How this generator works
A multiplier is drawn and multiplied by your base, so the result is exactly divisible by that base with nothing left over. Drawing the multiplier rather than drawing a value and rounding it to the nearest multiple matters at the edges: rounding makes the first and last multiples in a range half as likely as the ones in the middle.
Limitations and good to know
- The range you set applies to the result, so a large base with a narrow range may leave very few multiples to draw from.
- Zero is a multiple of every number and is excluded here, since it is rarely the intended answer.
- Negative bases give negative multiples; the divisibility holds either way.
