Question

find the lcm of x and y if xy=180 and hcf of (x,y)= 5

Answer 1

we know,
product is two numbers = HCF * LCM
180=5*LCM
LCM = 180/5
LCM =36

Answer 2

Given : xy= 180 and HCF (x,y) = 5

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) = 5

=> LCM ( x , y) . 5  = 180

Dividing both sides by 5

=> LCM ( x , y)     = 36

LCM ( x , y)     = 36
