Oh, dude, "relatively prime" just means two numbers have no common factors other than 1. So, numbers that are relatively prime with 18 are ones that don't share any factors with 18 besides 1. In this case, numbers like 1, 5, 7, 11, 13, 17, and so on are relatively prime with 18. It's like 18 is at a party, and these numbers are the cool kids who don't have any drama with it.
Numbers that are relatively prime with 18 are numbers that have no common factors other than 1. The prime factorization of 18 is 2 x 3^2. Therefore, numbers that are relatively prime with 18 are those that do not have 2 or 3 as factors. Some examples of numbers relatively prime with 18 are 5, 7, 11, 13, 17, and so on.
No.
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.
Any two prime numbers will be relatively prime. Numbers are relatively prime if they do not have any prime factors in common. Prime numbers have only themselves as prime factors, so all prime numbers are relatively prime to the others.
The GCF of 18 and 49 is 1. These numbers are relatively prime
Infinitely many numbers are relatively prime to 37. Because 37 is a prime number, all other numbers are relatively prime to it.
No.
No.
Any odd prime number.
4, 18

You can multiply the number 18 by different numbers that are relatively prime, for example by different prime numbers.
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

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.

You might be thinking of relatively prime numbers. Two numbers are considered relatively prime if their GCF is 1. 4 and 9 are relatively prime.
To have a gcf of 18 they must have one factor of 18 in common and no other factor, ie the second factor of the numbers must be relatively prime. The multiples of 18 between 200 and 300 are: 12 x 18 = 216 13 x 18 = 234 14 x 18 = 252 15 x 18 = 270 16 x 18 = 288 12 is relatively prime to 13 13 is relatively prime to 14, 15 & 16 14 is relatively prime to 15 15 is relatively prime to 16 (Pairs of numbers are being considered, so as 12 is relatively prime to 13, 13 is also relatively prime to 12 and thus is only listed when the numbers increase, ie under 12 and not under 13.) Thus the pairs: 216 & 234 234 & 252 234 & 270 234 & 288 252 & 270 270 & 288 all have a gcf of 18.
