The factors for 16 are 1, 2, 4, 8, 16. The two numbers (12 and 16) share common factors (1, 2, 4). The greatest of these is 4 and that is the greatest common factor.

## What is the LCM of 5 10 and 7?

Explanation: To find the LCM (Lowest common multiple) of a set of numbers, you first find the multiples of each number and then identify the smallest common one among the set. In this case, using 5 , 7 , and 10 . The smallest common multiple of each would be 70 .

## What is the LCM of 8 and 7?

multiples of 8 ⇒8,16,24,32,40,48,56,64,72…. so the lcm, I.e. least common multiple of 7 and 8 is, 56.

## How do we calculate LCM?

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
