Detailed Solution

Concep- Least Common Multiple, or LCM for short, is the lowest common multiple (common factor) among numbers. The approach incorporates fundamental factorization of the numbers to discover factors that are multiplied together to generate a number in order to determine the LCM of the provided numbers, which is the lowest common multiple that is divisible by all the numbers for which the LCM is being found. The LCM for any provided numbers that are zero while the LCM is being calculated will likewise be zero. Find the factors of the number first, as multiplying them all together results in the original number.
In order to obtain the answers to the provided numbers in this problem, first suppose that box and bye have a common factor.
Given:- L.C.M of three numbers is 12.
To find: The numbers
If the numbers are x, 2 x and 3 x.
 L. CM =12  
1×2×3×x=12  
6x=12  
x= 12 6 =2
