Fascinating Fact:

A skyscraper of 300 metres is about fifteen times taller than a wind turbine at 20 metres.

In KS3 Maths, mastering the 15 times table strengthens number sense. You’ll use place value and factors to split 15 into friendly parts (10 and 5), spot patterns in multiples, and apply these skills to everyday problems.

Key Terms

Multiple: A number in the 15 times table (15, 30, 45, 60, …).
Factor: A whole number that divides another exactly (for 15, the factors are 1, 3, 5, 15).
Common multiple: A number that is a multiple of two or more numbers (e.g., 30 is a common multiple of 5 and 15).

Frequently Asked Questions (Click to see answers)

What are quick ways to work out the 15 times table?

Use splitting: 15 × n = (10 × n) + (5 × n). Or double-and-add: 15 × n = (3 × n) × 5. Many learners also do 15 × n = (30 × n) ÷ 2.

How do I know if a number is a multiple of 15?

It must be divisible by 3 and by 5. Check it ends in 0 or 5, and the sum of its digits is a multiple of 3. If both are true, it’s a multiple of 15.

Where is the 15 times table used in real life?

Packs of 15 items, quarter-hour timing (15 minutes), price-per-15 deals, and seating in rows of 15 all rely on quick 15× facts for fast calculations.
