## Useful Information: Least common multiple (LCM) and greatest common divisor (GCD)

In math, the greatest common divisor (GCD), also known for us as the highest common factor (HCF) and the greatest common factor (GCF), of two or more non zero integers. It is the largest positive integer that can divides the numbers without a remainder.

In number theory and arithmetic, the least common multiple (also known as the smallest common multiple and the lowest common multiple) of two integers a and b. Usually it is denoted by LCM (a, b), is the smallest positive integer (SPI) that’s a multiple of both a and b. It’s familiar from grade school arithmetic as the lowest common denominator (LCD) that must be determined before two fractions can be added.
