This will only work in the following conditions: 1. The LCM of 3 numbers should be their product 2. The chosen number should perfectly divide the 3 numbers. If (1) is not true, common divisors should be taken only once. If (2) is not true the problem should be first solved for up to highest number which perfectly divides the product of 3 numbers, and then the leftover numbers should be considered.

This will only work in the following conditions:

If (1) is not true, common divisors should be taken only once.
