## Which is the greatest common factor in LCM?

For example, LCM (2,3) = 6 and LCM (6,10) = 30. The Greatest Common Factor (GCF) is also referred to as the Highest Common Factor (HCF) and Greatest Common Divisor (GCD). For two integers x and y, denoted GCF (x,y), the largest positive integer that divides evenly into two numbers with zero remainder.

## How to calculate the greatest common factor for two whole numbers?

Given two whole numbers, subtract the smaller number from the larger number and note the result. Repeat the process subtracting the smaller number from the result until the result is smaller than the original small number. Use the original small number as the new larger number.

Is there a way to find the least common multiple?

It is commonly denoted as LCM (a, b). There are multiple ways to find a least common multiple. The most basic is simply using a “brute force” method that lists out each integer’s multiples. As can be seen, this method can be fairly tedious, and is far from ideal.

### Which is the largest GCF of two numbers?

The GCF (GCD) of two or more numbers is the largest number that is evenly divisible by all numbers in the set with remainder zero. For example, for the set of numbers 12, 24 and 36 the GCF = 12.
