You need at least two numbers to find something in common, but I'll save you the trouble. The least common factor of any set of positive numbers is 1.
The least common multiples of the number 6 and 9 is 3.
6 is less than 21. Out of that set, 6 is the least number. The least common multiple of 6 and 21 is 42.
The Least Common Multiple (LCM) for 5 6 is 30.
because its the least common number that goes into 6 and 10
The least common multiple of the numbers 6 and 10 is 30.
The least common factor is: 1
That is impossible to answer, because you would have to have another number and 6 to find a least COMMON multiple.
30
The LCM is 18.
60
It is: 18
The common multiples of 3 and 6 are numbers that are divisible by both 3 and 6, such as 6, 12, 18, 24, etc. The least common multiple (LCM) of 3 and 6 is the smallest number that is a multiple of both 3 and 6, which in this case is 6. This is because 6 is the smallest number that both 3 and 6 can divide into without leaving a remainder.
