good idea. Example: a= b+c;
i think a good answer would be Ramanujan , the world famous Indian mathematician.
40 is not the LCM of 9 and 4.
The least common multiple, or LCM, is the smallest positive integer that all the members of a given set of numbers will divide into evenly with no remainder.
The LCM of 14 and 42 is 42.
As for example the LCM of 15 and 20 is 60
You can't do the LCM of 400 because you need two numbers to do the LCM of, for example, the LCM of 12 and 8 would be 24.
The LCM of any two prime numbers is their product as for example the LCM of 5 and 7 is 35
See the related links posted below. It is a good example of calculating the Least Common Multiplier.
The LCM stands for the lowest common multiple as for example the LCM of 3 and 5 is 15
The LCM is the higher number. The LCM of 3 and 9 is 9.
