1.

The product of two numbers is 210 and their HCF is 1.what is their LCM

Answer»

The formula for finding LCM in this QUESTION is

=> 1st no. * 2nd no. = LCM * HCF

=> 210 (Given in question) = LCM * 1 (Given in question)

=> LCM = 210/1 (TRANSPOSED 1 from LHS)

=> LCM = 210  

In other words, whenever HCF of 2 numbers is 1, then their product will be the LCM.
