Answer 1

Answer:

Factor of 12=2×2×3

Factor of 12=2×2×3Factor of 15=3×5

Factor of 12=2×2×3Factor of 15=3×5Factor of 21=3×7

Factor of 12=2×2×3Factor of 15=3×5Factor of 21=3×7HCF (12,15,21)=3

Factor of 12=2×2×3Factor of 15=3×5Factor of 21=3×7HCF (12,15,21)=3LCM (12,15,21)=2×2×3×5×7=420

Factor of 12=2×2×3Factor of 15=3×5Factor of 21=3×7HCF (12,15,21)=3LCM (12,15,21)=2×2×3×5×7=420(ii) 17, 23 and 29

Factor of 12=2×2×3Factor of 15=3×5Factor of 21=3×7HCF (12,15,21)=3LCM (12,15,21)=2×2×3×5×7=420(ii) 17, 23 and 29Factor of 17=1×17
