Q. The product of HCF and LCM of 18 and 15 is
✅ Correct Answer: (D)
270
Explanation: HCF of 18 and 15
18 = 2 x 3 x 3
15 = 3 x 15 = 3
LCM of 18 and 15 = 2 x 3 x 3 x 5 = 90
∴ Product of HCF and LCM of both numbers = 3 x 90 = 270

HCF of 18 and 15
18 = 2 x 3 x 3
15 = 3 x 15 = 3
LCM of 18 and 15 = 2 x 3 x 3 x 5 = 90
∴ Product of HCF and LCM of both numbers = 3 x 90 = 270
18 = 2 x 3 x 3
15 = 3 x 15 = 3
LCM of 18 and 15 = 2 x 3 x 3 x 5 = 90
∴ Product of HCF and LCM of both numbers = 3 x 90 = 270
