In order to have a common multiple, you need to be talking about two or more numbers. The question only asked about one number, 18, so there is no correct answer.
A common multiple of 16 and 18 is 144.
6 is a factor of 18, so the least common multiple is 18.
126 is the Lowest Common Multiple of 18 and 42
the highest common multiple of 14 and 18 is 2
Least Common Multiple (LCM) for 18 36 is 36.
Any multiple of 18 can be common.
The least common multiple of 18 , 56 = 504
A common multiple of 16 and 18 is 144.
6 is a factor of 18, so the least common multiple is 18.
Highest common multiple of 24 and 18 is 6.
Any set of factors that had 18 as a common multiple would also have multiples of 18 in common, so 18 can't be greatest. 9 and 6 have 18 as their least common multiple.
The Least Common Multiple (LCM) for 3 18 is 18.
The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 3 and 18 is 18.
Least common multiple of 18 and 34 is 306.
the first 2 common multiple of 18 and 32 is 288 and 576
The Least Common Multiple (LCM) for 16 18 is 144.
The Least Common Multiple of 18 and 21 is 126.
