1,2,3
1, 660, 5580
Multiples of 1 include 1, 2 and 3. For them to be common, they need to be compared to another set of multiples.
6,12,18
7, 14, 21
9, 18, 27
2, 4, 6
3, 6, 9
12, 24, and 36
The common multiples of any two or more numbers are the multiples of their lowest common multiple.lcm(3, 4, 5) = 60→ first three common multiples are:60 x 1 = 6060 x 2 = 12060 x 3 = 18060, 120, 180
They are 36*1, 36*2 and 36*3.
To find the answer, multiply whatever the number is by 1, 2 and 3.
