All numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples. The smallest of these is known as the least common multiple. Common multiples of 3 and 4 include 12, 24, 36 and so on. The LCM of 3 and 4 is 12.

The common multiples of 15 and 25 are all multiples of their LCM, which is 75. So, the common multiples are 75, 150, 225, 300, 375, 450, 525, 600, and so on.

To find common multiples of two numbers, you first have to break them down into their prime factors. In this case, the prime factors of 30 and 75 are: 30 = 2x3x5 75 = 3x5x5 The next step is to identify and discard any duplicate common factors. In this case both numbers have a 3 and a 5 as prime factors, so we can discard one of each. Taking all the other prime factors (2, 3, 5 and 5) and multiplying them together will give us the LCM: 2x3x5x5 = 150. Thus the lowest common multiple of 30 and 75 is 150. To find other common multiples, you just multiply this LCM by any integer. For instance, 150x2, 150x3, 150x4 and so on. This means the first few common multiples of 30 and 75 are 150, 300, 450 and 600.

The common factors of 6 and 15 is 1 and 3 that's all

The common factors of 10 and 15 are: 1 and 5.

The LCM of 15 and 33 is 165Break them down into prime factors:33 = 3 x 1115 = 3 x 5.Multiply all the factors apart from one instance of any that appear in both 33 and 15:3 x 5 x 11 is the answer

There are infinite common multiples for a set of numbers. So it is not possible to write down all the common multiples. Some common multiples of 15, 30 and 45 are 90, 180, 270, 360,... There is another way to find common multiples: Write the multiples of LCM(15, 30, 45). Actually the common multiples of a set of numbers are the multiples of their LCM. LCM of 15, 30 and 45 is 90. And the multiples of 90 are 90, 180, 270, 360, 450, 540,... which are the common multiples of 15, 30 and 45.

Common denominators of 8 and 15 are 120 and all its multiples.

Multiples of 15 include 15, 30 and 45. For them to be common, they need to be compared to another set of multiples.

No, they are factors of 15. Factors go into numbers, numbers go into multiples.

Do you mean common multiples? If so, then 30, 60, 90 etc. are common multiples of 30 and 5. If you mean multiples of 5 and factors of 30, that's 5, 15 and 30.
