Question

If hcf of two numbers is 20 and their product is 2200 then find lcm

Answer 1

hcf ×LCM=product of given number

20×LCM=2200

LCM=100

Answer 2

Solution:

Let a and b are two numbers,

their HCF = h , LCM = l.

l × h = a × b

Here, given

a × b = 2200

h = 20

Now ,

l = (a×b)/h

=> l = 2200/20

=> l = 110

Therefore,

LCM = l = 110
