the above is true if you wanted the multiples of the numbers separately. If you were looking for the three first COMMON multiples of the numbers, they are...
30, 60, 90.
The first (or least common) multiple of two numbers is also equal to the product of the two numbers divided by the greatest common factor of the numbers. Since 5 is prime, and 6 is NOT a multiple of 5, then the greatest common factor is 1. Thus, the least common multiple is 30.
To find the second multiple, take the first times 2, for the third, take the first times 3, etc......

What is the sum of the first 4 multiples of 5?
5 + 10+15+20=50 ans
What are the five common multiples of 5 and 6?
The common multiples of 5 and 6 are the multiples of their lowest common multiple (which is 30), so there are infinitely many common multiples of 5 and 6. The first five are: 30, 60, 90, 120, 150.
What are the three frist multiples of 3 and 9?
The first three multiples of 3 are 3, 6, 9 The first three multiples of 9 are 9, 18, 27 As the lowest common multiples of 3 and 9 is 9, the common multiples of 3 and 9 are the multiples of 9, thus: The first three common multiples of 3 and 9 are 9, 18, 27
