11 is the Prime number.
11/18 cannot be simplified - 11 is a prime number !
2 + 5 + 11 = 18 2 + 3 + 13 = 18
For a start, you can discard all the even numbers - those that end with 2, 4, 6, 8, 0 - except for the number 2 itself (which in this case, isn't in the list). This only leaves you with the number 11 - which happens to be a prime number.
7 & 11 added together total 18.
A prime number has only 2 factors which are 1 and itself. 11 and 7 equal 18 when added.
Lots of numbers are. To be relatively prime, they would have to have only the number 1 as a common factor. So any number that has any of 2, 3, 6, 9 or 18 as factors are not relative prime to 18. So numbers such as 5, 7, 11, 13 and 17 are relatively prime with 18.
The first prime number after 18 is 19.
A twin prime is a prime number that differs from another prime number by two. 18 is not a prime; it is a composite number. All even numbers are composites and 18 is an even number.
18 is not a prime number so no number can have 18 as a prime factor.
18 is a composite number because it has at least one positive factor other than one or itself.
2 is a prime number. 18 is a composite number.
There is no prime number that goes into 32. For 18, there is the number 3. So, there is NO prime number that goes into both 18 and 32.Another Answer:-2 as a prime number will go into 18 and 32 evenly
