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
12 and 24
24 and 48
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).
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.
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.
36, 72.
They are 12 and 24
60 and 180 are two.
There is an infinite number of common multiples for 4 and 11. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
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).
