Any multiple of 180.
The least common multiple of 4 , 5 , 9 , 18 = 180
The least common multiple of the numbers 4, 5 and 9 is 180.
5 is not a common multiple.
The LCM of 9, 5, and 4 is 90 180.
900 is the least common multiple of 2, 3, 4, 5, 9, and 100.
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 4, 5, and 9 is 180.
The lowest common multiple of 4, 2, 9, 5 and 100 is 900. Since 4, 2 and 5 are factors of 100, you can ignore them. Then all you have to do is multiply 9 times 100.
To find a number that is not a common multiple of 4 and 9, we need to consider the multiples of each number. The multiples of 4 are 4, 8, 12, 16, 20, 24, ... and the multiples of 9 are 9, 18, 27, 36, 45, ... The first number in the list of multiples of 4 that is not a multiple of 9 is 4. Therefore, 4 is a number that is not a common multiple of 4 and 9.
