Multiples of 7 include 7, 14, 21, 28 and so on. For them to be common, they need to be compared to another set of multiples.
Multiples of 7 that are less than 60 are 7, 14, 21, 28, 35, 42, 49, 56.Multiples of 14 that are less than 60 are 14, 28, 42, 56. Common multiples that are less than 60 are 14, 28, 42, and 56.
7, 14, 21, 28, 35, 42
The least common multiple of 14 and 21 is 42.Look at the multiples of 14. They are 14, 28 and 42.Now clearly 14 and 28 are can't be multiples of 21 also so throw them out as candidate for the LCM. However, the next number. 42 is 21x2.We know there is no smaller common multiple because 21x1 did not work so we are done.The LCM is: 42
