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.

What numbers are relatively prime with 18?
All odd numbers that can not be divided by 3 evenly would be relatively prime with 18.
Are 25 and 18 relatively prime?
Yes, they are. 5 is the only prime factor of 25 and 5 is not a factor of 18, so they have no prime factors in common, which is what relatively prime means.
Are 12 and 51 relatively prime?
They are not relatively prime. To be relatively prime, the only common factor they could have would be the number 1. Both also have the number 3 as a common factor, so they are not relatively prime.
Is 18 and 49 relatively prime?
Yes
Is 18 and 105 relatively prime numbers?
No.
What numbers are 18 relatively prime to?
Any odd prime number.
Is 18 and 33 relatively prime?
No. Both 18 and 33 can be divided by 3, which means that they are not relatively prime.(TIP When someone asks you if the numbers are relatively prime think of a number that both numbers can be divided by to get a whole number. With that you should be able too see strait away which numbersare relatively prime.)(Relatively prime means any amount of numbers that can only be divided by 1 and themselves )Hope I helped! :) XD
How many prime numbers in 100 are relatively prime?
Any prime number is relatively prime to any other prime number.
Find 3 numbers whose GCF is 18?
You can multiply the number 18 by different numbers that are relatively prime, for example by different prime numbers.
What numbers are relatively prime with 18?
All odd numbers that can not be divided by 3 evenly would be relatively prime with 18.
Is 18 relatively prime?
Relatively Prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
Are 100 and 202 relatively prime?
No, 100 and 202 are not relatively prime. Relatively prime numbers only have the number 1 as a common factor. The number 1 is a common factor for them, but the number 2 is another common factor that they have, so they are not relatively prime.
Are 18 and 45 relatively prime?
No, they are not.
Are 8 and 18 relatively prime?
no
What is a number that is relatively prime?
A number is relatively prime to another number or set of numbers when their GCF is 1.
Are 25 and 18 relatively prime?
Yes, they are. 5 is the only prime factor of 25 and 5 is not a factor of 18, so they have no prime factors in common, which is what relatively prime means.
What number is relatively prime to forty?
41 is relatively prime.
