Question

if AB=180 AND LCM(a, b)=60 then find HCF (a, b)​

Answer 1

Answer:

3

Step-by-step explanation:

Given that:

Let the two number given be a and b.

LCM of a and b = 60.

Product of a and b = 180.

To find:

HCF of a and b.

Proof:

We know that, when two number are given,

Product of the two number=HCF×LCM of the two numbers

On substituting the given values in the formula above,

60×HCF = 180

HCF = 180/60

HCF = 3.

Therefore, the value of the HCF of a and b is 3.

Hope it helps you.

Good Luck.
