It is 210.

The LCM is: 42

126

It is: 126

The common multiples of 7, 14, and 21 are the infinite set of multiples of their least common multiple, which is 42. So the common multiplesof 7, 14, and 21 are 42, 84, 126, 168, and so on.Any multiple of 42.

You can have three common multiples, but only one can be least and that's 126. Others include 252 and 378.

The least common multiple (LCM) of two numbers is the smallest positive rational number (not zero) that is a multiple of both. Multiples of 14 are: 14, 28, 42, 56, etc. Multiples of 21 are: 21, 42, 63,etc. The least common multiple of 14 and21 is the smallest one of those: 42

The multiples of 7 are 7, 14, 21, 28, 35, 42, etc.The multiples of 14 are 14, 28, 42, etc.The multiples of 21 are 21, 42, etc.The least common multiple (LCM) of 7, 14, and 21 is 42

Multiply 21 and 11 to get a common multiple. Since 21 and 11 have no common factors, that also happens to be the least common multiple.All other common multiples are multiples of this least common multiple.

The least common multiple of 14 and 21 is 42.Look at the multiples of 14. They are 14, 28 and 42.Now clearly 14 and 28 are can't be multiples of 21 also so throw them out as candidate for the LCM. However, the next number. 42 is 21x2.We know there is no smaller common multiple because 21x1 did not work so we are done.The LCM is: 42

The least common multiple of the numbers 72 and 21 is 504.

The Least Common Multiple (LCM) of (3,7) is 21.
