Multiples of 5 include 5, 10 and 15. For them to be common, they need to be compared to another set of multiples.
list the first 10 multiples of 15
30 60 90
60, 120 and 180
The first five multiples of 5 are 5, 10, 15, 20 and 25. For them to be common, they need to be compared to another set of multiples.
The Least Common Multiple (LCM) for 8 10 15 is 120.
Since 3 is a factor of 15, the first three common multiples of 3 and 15 are 15, 30, and 45.
A word problem that involves common multiples could be, "Whatare the common multiples of 10 and 15?"
The first four multiples of five: 5, 10, 15, 20
the first two common multiples of 15,27 are 135,270
Oh, isn't that just a happy little question! The first common multiples of 2, 3, and 5 are like little friends dancing together. Let's see, the first three common multiples are 30, 60, and 90. They all come together in harmony, just like colors on a beautiful canvas.
They are 30, 60 and 90.
