90, 180 and 270
Since 3 is a factor of 15, the first three common multiples of 3 and 15 are 15, 30, and 45.
15, 30, 45
15 and 30
Multiples of 15 include 15, 30 and 45. For them to be common, they need to be compared to another set of multiples.
30 and 60
Ans: 15, 30 and 45 Prime factorization of 3 and 15 3: 3 15: 3 x 5 15, 30 and 45. Hi My names Bob
There are infinite common multiples for a set of numbers. So it is not possible to write down all the common multiples. Some common multiples of 15, 30 and 45 are 90, 180, 270, 360,... There is another way to find common multiples: Write the multiples of LCM(15, 30, 45). Actually the common multiples of a set of numbers are the multiples of their LCM. LCM of 15, 30 and 45 is 90. And the multiples of 90 are 90, 180, 270, 360, 450, 540,... which are the common multiples of 15, 30 and 45.
15, 30, 45
30 60 90
15, 30, and 45 are.
30, 60, 90
30 is a multiple of 30 and 15.
