Question

The hcf of two numbers is 18 and their product is12960.find their lcm

Answer 1

We know HCF x LCM = Product of two numbers 
∴18 x LCM = 12960
⇒LCM = 12960 / 18
= 720 Answer.

Answer 2

Hey there!

=================================

Formula Used :-

⇒ H.C.F * L.C.M = PRODUCT OF NUMBERS

⇒ When Term in multiplication transfered from L.HS to R.H.S, it becomes a term in division and vice - versa

=================================

Given ➺

H.C.F = 18

Products of Numbers = 12960

⇒ H.C.F * L.C.M = PRODUCT OF NUMBERS

18 * L.C.M = 12960

L.C.M = 12960/18

= 720

hope helped!
