1,2,3,5,15The lowest common multiple of 30 and 45 is 90

The LCM is 30.

60 is the lowest common multiple. actually no, 30 is.

The common multiples of 5 and 6 are the multiples of their lowest common multiple (which is 30), so there are infinitely many common multiples of 5 and 6. The first five are: 30, 60, 90, 120, 150.

Do you mean the lowest common multiple? If so then it is 30

210

10, 20, 30 The common multiples of 5 and 10 are multiples of their lowest common multiple. The lcm of 5 and 10, is 10. Thus the first three common multiples are 10, 20, 30.

Since the lowest common multiple of 3 and 5 is 15, the common multiples of 3 and 5 are the multiples of 15: 30, 45, 60, 75, 90, etc...

Multiples of 6: 6, 12, 18, 24, 30, 36, ................ Multiples of 10: 10, 20, 30, 40, ................ 30 is the LCM (least common multiple) of 6 and 10. correct but LCM stands for lowest common multiple...

The Least Common Multiple (LCM) for 2 3 5 is 30.

Since 30 is a multiple of 6, all multiples of 30 are common.

210, 420, 630, 840, 1050 Five common multiples. Only one can be least.

3, 6, 9, 12, 15, 18, 21, 24, 27, 30

The multiples of 10 are 10, 20, 30, 40, 50, 60, 70, etc ...The multiples of 12 are 12, 24, 36, 48, 60, 72, etc ...The lowest common multiple of 12 and 10 is 60.

The lowest common multiple of 5 and 6 is 30, as it is the first number that appears in both the 5 times table (multiples of 5) and the 6 times table (multiples of 6).

10, 20, 30 and so on.The lowest common multiple of 5 and 10 is 10

Multiples of 30 include 30, 60, 90, 120 and so on. For them to be common, they need to be compared to another set of multiples.

The multiples of 3 up to 30 are: 3,6,9,12,15,18,21,24,27,30.The multiples of 5 up to 30 are: 5,10,15,20,25,30.The only common multiples are 15 and 30.The LCM is: 30

The LCF is 1. The GCF is 3.

LCM = Lowest Common Multiple. This is the smallest number that is common amongst the multiples of two of more other numbers. For example: The multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, ... The multiples of 5 are: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, ... The common multiples of 3 and 5 are: 15, 30, 45, ... The lowest common multiple of 3 and 5 is the smallest of these, namely 15. An example of its use is for adding fractions as using the lowest common multiple of all the denominators ensures the numbers do not get too big (and cumbersome)

There is an infinite number of common multiples for 18 and 30 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 of 18 and 30 is 90.

There is an infinite number of common multiples for 33 and 30. 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 of 33 and 30 is 330.

The common multiples of 12 and 30 are 60, 180, 240, etc.
