Since 13 is a Prime number (i.e., 13 is the only factor of 13), any number that is not a multiple of 13 is relatively prime to it.
No, 13 and 39 are not relatively prime. 13 is a factor of 39.
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.
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.
13 is a prime number
An easy way to find a number relatively prime to another number is to find a nearby prime number. For example, 53 is relatively prime with 50. The following pairs are relatively prime. 3, 50 19, 50 37, 50 49, 50 50, 69 50, 201 50, 341 Any number that is not divisible by 2 or 5 will be relatively prime to 50.
13 and 4 are relatively prime.
13 and 24 are relatively prime.
It can be. Since 13 is a prime number, it is relatively prime to all other numbers except for multiples of 13.
No. Numbers that are relatively prime, only have the number 1 as a common factor. 13 and 78 have 1 and 13 as common factors, so they are not relatively prime.
yes
The GCF of 26 and 65 is 13. 13 is a prime number. "Relatively prime" refers to numbers whose GCF is 1.
As 13 is prime and is not a factor of 24, then they are relatively prime
Yes, 13 and 17 are relatively prime.
No, they are not relatively prime.
No, 13 and 39 are not relatively prime. 13 is a factor of 39.
Yes, they are relatively prime.
Yes, they are relatively prime.
