Class 10 Maths CBSE Previous Year Question:-

If xy = 180 and HCF(x,y) = 3, then find LCM(x,y). Class 10 mathematics chapter 1 real numbers important question cbse board exam previous year question

Video Solution:-

Solution

Given that xy = 180 and HCF(x,y) = 3

we are required to find LCM(x,y)

Using formula

HCF ✕ LCM = Product of two numbers

3 ✕ LCM(x,y) = xy

3 ✕ LCM(x,y) = 180

LCM(x,y) = 180

3

So, LCM(x,y) = 60
