What are the first 15 multiples of four
25 and 50
The sum of the first 25 numbers is 25*26/2 = 325 So the sum of the first 25 multiples of 12 is 325*12 = 3900
The first four are; 4,8,12,16
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.
30, 60, 90, 120, 150
The first four multiples of 20 are: 20 40 60 80
