The LCM of two numbers is 2310 and their HCF is 30. If one of the numbers is 7 × 30, find the other number.
A
220
B
330
C
425
D
512
Correct Option:
B
Explanation
LCM × HCF equals the product of the two numbers. Thus, the product is 2310 × 30 = 69300. One number is 7 × 30 = 210, so the other is 69300 ÷ 210 = 330.
