The Greatest Common Factor, the GCF, is the biggest (“greatest”) number that will divide into (that is, the largest number that is a factor of) both 2940 and 3150. On the other hand, the Least Common Multiple, the LCM, is the smallest (“least”) number that both 2940 and 3150 will divide into.
How are GCD and LCM related?
The least common multiple (LCM) of two integers is the smallest positive integer that is a multiple of both. The greatest common divisor (GCD) of two integers is the largest positive integer dividing both. The product of the two numbers is the product of the LCM and the GCD.

What’s the difference between a HCF and a LCM?
The HCF defines the greatest factor present in between given two or more numbers, whereas LCM defines the least number which is exactly divisible by two or more numbers. HCF is also called the greatest common factor (GCF) and LCM is also called the Least Common Divisor.
How to find the least common multiple ( LCM )?
To find either the Least Common Multiple (LCM) or Greatest Common Factor (GCF) of two numbers, you always start out the same way: you find the prime factorizations of the two numbers. Then (here’s the trick!) you put the factors into a nice neat grid of rows and columns, compare and contrast, and then, from the table, take only what you need.
What does it mean when a number is the GCF?
Since 1 divides into everything, then the greatest common factor in this case is just 1. When 1 is the GCF, the numbers are said to be “relatively” prime; that is, they are prime, relative to each other.
