This article is focused on multiples of 18 and its common multiples with other numbers such as 3, 12, 14, 15, 30 and 32.
Multiples of 18 Chart
Before we start finding common multiples of 18 with other numbers, let’s have a look at chart containing first 100 multiples of 18.
Common Multiples of 18
Common Multiples can be found in two ways.
First way is to find multiples of both numbers individually and then finding similar numbers in that list.
Another method is to find least common mulitple (LCM) of both numbers and then finding multiples of LCM.
Both methods are super easy. Let’s solve problems now.
Finding Common Multiples of 18 with 3
As 18 is 6th multiple of 3 and according to Laws of Multiples if one number is multiple of other one, LCM will be greater number i.e. 18 in our case. so,
Common Multiples (12 and 18)
In order to find common multiples of these both numbers, we will first find LCM of both numbers and then will find multiples of LCM.
Common Multiples of 18 and 14
Let’s find LCM first.126 is least common multiple (LCM) of 14 and 18
Common Multiples of 15 and 18
As, we know now that in order to find multiples of any number, we first find LCM. Let’s do that for give numbers too.
Multiples of 18 and 30
As 90 is least common multiple of both numbers so all its multiples will be Common multiples of 18 and 30
Multiples of 18 and 32
This is last problem of this article. We will solve this problem with same method we solved other problems. Let’s do that now.
