11. Answer:
LCM = 300
Explaination:
We will learn the relationship between H.C.F. and L.C.M. of two numbers.
The product of highest common factor (H.C.F.) and lowest common multiple (L.C.M.) of two numbers is equal to the product of two numbers.
H.C.F. × L.C.M. = First number × Second number
10 * LCM = 3000
LCM = 300
12: Answer: Second number = 352
Explaination:
Given lowest common multiple (L.C.M.) = 1760
Highest Common Factor (HCF) =32
First Number = 160
We find the second number.
Use the relation:
H.C.F. × L.C.M. = First number × Second number
32*1760 = 160 * second number
Second number = 352
