Twice and three times as much as the previous common multiple respectively
The LCM is 30. The next common multiple is 60.
You have to have two different numbers to find common multiples
Two common multiples of 21 and 15 are 105 and 315.
The two common multiples of three and five are: 15 and 30 ^-^
lcm of 12 and 16 is 48, next lcm is 96
Those are known as "common multiples". The smallest POSITIVE of these common multiples is called the "least common multiple".
They are the common multiples of the two numbers.
The way to solve this is as follows:Find the least common multiple of the two numbers.Multiply this least common multiple by 2 and by 3, to get the next two common multiples.
60 and 120 are the two lowest common multiples.
common multiples
The common multiples of 9 and 16 are 144, 288, 432 and so on.
The two smallest multiples of 10 are 10 and 20. For them to be common, they would need to be compared to another set of multiples.
