Multiples of 4 include 4, 8, 12, 16, 20 and so on. For them to be common, they need to be compared to another set of multiples.
lcm(4, 9) = 36 → the two least common multiples (ie the first two common multiples) of 4 and 9 are 36 and 72.
21 and 28
24 and 48
12 and 24
To have a common multiple, there have to be two or more numbers. For example, common multiples of 4 and 8 are 8, 16, 32, 48, etc. The Least Common Multiple of 4 and 8 is 8.
There is an infinite number of common multiples for 4 and 20. A common multiple of any two numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
52 and 56 are multiples of 4 and have 1, 2 and 4 in common. 54 and 57 are multiples of 3 and have 1 and 3 in common.
They are 12 and 24
60 and 180 are two.
36, 72.
The common multiples of 11 and 4 are 88, and 4.
There is an infinite number of common multiples for 4 and 3. A common multiple of any two numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
