Question

lf xy= 180 and HCF (X,y)=3 then find the LCM (X,y)​

Answer 1

Answer:

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

To Find :  lcm(x, y)​

Solution:

LCM - Least common Multiplier

HCF - Highest Common Factor  

LCM ( x , y) . HCF ( x , y)   = x . y  

xy= 180

HCF (x,y) = 3,

=> LCM ( x , y) . 3  = 180

Dividing both sides by 3

=> LCM ( x , y)     = 60

LCM ( x , y)     = 60
