There cannot be common multiples of a single number such as 345. Common multiples are multiples that two or more numbers have in common.
You have to have two different numbers to find common multiples
The two common multiples of three and five are: 15 and 30 ^-^
Two common multiples of 21 and 15 are 105 and 315.
They are the common multiples of the two numbers.
Those are known as "common multiples". The smallest POSITIVE of these common multiples is called the "least common multiple".
common multiples
60 and 120 are the two lowest common multiples.
lcm(4, 9) = 36 → the two least common multiples (ie the first two common multiples) of 4 and 9 are 36 and 72.
A single number cannot have common multiples, common multiples can only be shared by two or more numbers.
