Ques:- The H.C.F. and L.C.M. of two numbers are 12 and 336 respectively. If one of the numbers is 84, the other is
A. 24
B. 36
C. 48
D. 72
Right Answer:
We are given:
HCF = 12
LCM = 336
One number = 84
We are to find the other number.
🧠 Concept:
We use the fundamental relation between two numbers, their HCF and LCM:
HCF×LCM=Product of the two numbers\text{HCF} × \text{LCM} = \text{Product of the two numbers}
🔢 Step-by-step Calculation:
Let the other number be x.
We are given:
12×336=84×x12 × 336 = 84 × x 4032=84×x4032 = 84 × x
Now solve for x:
x=403284=48x = \frac{4032}{84} = 48
✅ Final Answer:
The other number is 48.
🧪 Check (optional):
HCF of 84 and 48 = 12
LCM of 84 and 48 = (84 × 48) / 12 = 4032 / 12 = 336 ✅
Hence, correct!
