The LCM of 3 and 10 is 30.

The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 3 and 10 is 1. So, the least common multiple is 3 x 10 ÷ 1 = 30.

The word "least" is a superlative. What that means is that there can be only one least - not more. So there are not least common multiples of 10 and 3: there is just one. And that is 30.

The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The least multiple of a number is itself.
