There is an infinite number of common multiples for 5 and 8. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple (LCM) of 5 and 8 is 40.
All the common multiples of a set of numbers are the multiples of their lowest common multiple: lcm(5, 8, 10) = 40 → first three common multiples are 40, 80, 120
The common multiples of 5 and 8 are the multiples of their lowest common multiple; lcm(5, 8) = 40 → the first five common multiples of 5 and 8 are: 40, 80, 120, 160, 200.
Lowest Common MultipleThe smallest common multiple of two or more numbers is called the lowest common multiple (LCM). E.g. Multiples of 8 are 8, 16, 24, 32, …Multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, …In general:To find the lowest common multiple (LCM) of two or more numbers, list the multiples of the larger number and stop when you find a multiple of the other number. This is the LCM.Example 3Find the lowest common multiple of 6 and 9.Solution:List the multiples of 9 and stop when you find a multiple of 6.Multiples of 9 are 9, 18, …Multiples of 6 are 6, 12, 18, …Example 4Find the lowest common multiple of 5, 6 and 8.Solution:List the multiples of 8 and stop when you find a multiple of both 5 and 6.Multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, …Stop at 120 as it is a multiple of both 5 and 6.So, the LCM of 5, 6 and 8 is 120.
There is an infinite number. the LCM is 72
