Best Answer

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

Yes, 33 and 56 are relatively prime.

No, they are not relatively prime.

It can be. 28 is relatively prime to 33.

no

The GCF is 33, which means they are not relatively prime.

Yes, e.g. 3 and 5 are relatively prime, 27 (33) and 25 (52) are relatively prime...

yes

Yes.

All odd numbers that can not be divided by 3 evenly would be relatively prime with 18.

Yes, e.g. 3 and 5 are relatively prime, 27 (33) and 25 (52) are 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.

No, they are not.

No.

1 It is a relatively prime number.

Yes.

Yes

No.

No.

Any odd prime number.

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.

no because it is just not

4, 18

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.

In order to be relatively prime to 12, it can't have the factors 2 or 3. Let's try 5^2 x 7^2 x 11. 13475 has three prime factors, 18 divisors, and is relatively prime to 12.

To find the prime and composite factors of a number, list all the factor pairs of the number. Then, go through them and list the primes and composites. 33 1 x 33 3 x 11 The prime factors are 3 and 11. The composite factor is 33. 1 is neither prime nor composite. 18 1 x 18 2 x 9 3 x 6 The prime factors are 2 and 3. The composite factors are 6, 9, and 18.
