Multiples of 1 include 1, 2 and 3. For them to be common, they need to be compared to another set of multiples.

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.
