The first 5 multiples of 5 are: 5, 10, 15, 20, 25 The first 5 multiples of 9 are: 9, 18, 27, 36, 45 The first 5 multiples of both 5 and 9 are: 45, 90, 135, 180, 225
The lowest common multiple is 18. The first four common multiples are thus the first four multiples of 18 and are: 18, 36, 54 and 72.
Any multiple of 180

-15
The first 5 multiples of 4 and 20 are 20, 40, 60, 80, 100
The first 3 multiples of 4 are: 4, 8, and 12.The first 3 multiples of 9 are: 9, 18, and 27.
It's 2 because 18 ,20,and 32 are all multiples of 2 and 2 is the smallest number that they are all multiples of.
