Real-World Applications
Tiling Problems
Problem: A room is 12m × 18m. What's the largest square tile that fits perfectly?
Solution: Find HCF(12, 18) = 6. Use 6m × 6m tiles.
Event Scheduling
Problem: Bus A comes every 15 minutes, Bus B every 20 minutes. How often do they arrive together?
Solution: Find LCM(15, 20) = 60. They meet every 60 minutes.
Simplifying Fractions
Problem: Simplify 48/72
Solution: Find HCF(48, 72) = 24. So 48/72 = 2/3
