Maths Quiz - Level 3-4 Algebra - Multiples (Questions)

In the awesome world of KS3 Maths, factors and multiples take the stage. But what's the difference? It's like a maths dance – factors are the numbers that can divide into another number, and multiples are what you get by multiplying a number.

Picture this: if a number has friends in a times table, those friends are its factors. On the flip side, every number in a times table is a buddy of that number – they're multiples. Like, 8 hangs out with 1, 2, 4, and 8 in the times tables club. So, 1, 2, 4, and 8 are factors, and 8 is their multiple. Got it?
