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.

Are 30 and 2 multiples of 60?
There is an infinite number of common multiples for 30 and 60. 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). However, the least or lowest common multiple (LCM) of 30 and 60 is 60.
What factor does 30 and 60 have in common?
Since 30 is a factor of 60, all of its factors are common.
What has factors 2 and 5?
There are infinetly many numbers which have 2 and 5 as their factors. Some examples are 10, 20, 30, 40, etc. 2 and 5 both are prime numbers and their common multiples are the multiples of 2 x 5 = 10. So all the multiples of 10 have 2 and 5 as their factors. However if consider 2 and 5 as the only two proper factors, then the required number is 10.

What is the common multiple of 15 30 and 45?
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.

What are the multiples that 30 and 36 have in common?
In order to find the common multiples of two numbers you first need to express them as the product of their prime factors: 30 = 2x3x5 36 = 2x2x3x3 The next step is to identify any common factors. In this case, both numbers have a 2 and a 3 as prime factors, so we can discard one of each. Take all the remaining prime factors (2, 2, 3, 3 and 5) and multiply them together to get the LCM: 2x2x3x3x5 = 180. To find other multiples that 30 and 36 have in common, you multiply this number by any integer (2, 3, 4...) Thus the first few common multiples of 30 and 36 are: 180, 360, 540, 720...
