Two numbers have a 375 LCM and a 15 HCF. What is the other number if one of the numbers is 45?
Given:
LCM of two numbers = 375
HCF of two numbers = 15
One number = 45
Formula used:
LCM × HCF = a b
Where,
a is first number.
b is second number.
Solution:
LCM × HCF = a b
a = 45
375 × 15 = 45 × b
5625 = 45 × b
b =
So, the other number is 125.
Thus, the correct answer is (b).
