If L.C.M. (150, 100) = 300, then find H.C.F. (150, 100).


Options:
A .   25
B .   50
C .   45
D .   75
Answer: Option B
:
B

Given: L.C.M. (100,150) = 300
We know that product of two numbers is equal to the product of their HCF and LCM.
Product of numbers 100 and 150 = HCF × LCM
100×150 = HCF × 300
HCF = 100×150300
HCF = 15000300
HCF = 50
HCF of 100 and 150 is 50.
