Bells that ring together again, runners who meet at the start, the biggest can that empties two tanks, the largest tile for a floor — every one of these is an HCF or LCM question in disguise. Decide which one, then use prime factors.
✓ You passed this lesson’s test.
LCM or HCF? — “things that meet again → LCM; the biggest size that fits exactly → HCF”
Use it for: Timetables, traffic lights, cutting cloth or rope into equal pieces, tiling a floor, and HCF/LCM word problems in tests.
🧮 Check your own sums with the free HCF and LCM calculator — it shows the working.
Check: 24 ÷ 6 = 4, 24 ÷ 8 = 3, 24 ÷ 12 = 2 — and no smaller number works for all three ✓
