The first 5 multiples of 22 are: 22, 44, 66, 88, and 110.
22, 44, 66, 88, 110.
33, 66, 99, 132, 165.
Only one can be least. That's 66. More common multiples add 66 to that. 66, 132, 198, 264, 330
They are the first three multiples of LCM(5, 9), that is, the first three multiples of 45.
The first 5 common multiples are: 7x20 = 140 2x7x20 = 280 3x7x20 = 420 4x7x20 = 560 5x7x20 = 700
33, 66, 99, 132, 165.
26, 52, 78, 104, 130.
The first 5 common multiples are the first 5 multiples of their lowest common multiple (LCM) LCM(9, 10) = 90 → first 5 common multiples are 90, 180, 270, 360, 450.
