In order to find the Least Common Multiple (LCM) of a number, there are several ways to determine it.
Listing method:
List the multiple of the numbers ascendingly.
7, 14, 21, 28, 35, 42, 49
14, 28, 42, 56, 70, 84, 98
It can be seen in the listing method that 7 is a multiple of 14, therefore the Least common multiple of 7 and 14 is 14.
Factor method
Check if the two numbers are a factor of one another, it can be done by dividing the smaller number with the larger number.
Dividing 14 by 7, we get an answer of 2 meaning that 14 is a multiple of 7.
Therefore the Least Common Multiple of 7 and 14 is 14.
