No.
no
Yes, 6 and 35 are relatively prime because they do not share any prime factors
Yes.
because they are just not
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.
A number cannot be relatively prime number by itself. It can only be relatively prime in the context of (relativeto) another number. That requires the two numbers not to have any prime factors in common.
62 is composite because it can be multiplied by one and other numbers. 1*62=62, 2*31, 62*1=62 if it was prime, then it would just be 1*62=62.
4 and 5 5 and 6 6 and 7
The numbers are relatively prime, or co-prime.
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.
Numbers are relatively prime if the only factor they have in common is 1. The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. The factors of 49 are 1, 7, and 49. The only common factor is 1. Therefore, 48 and 49 are relatively prime. Also, any two numbers whose difference is 1 are always relatively prime.
The GCF of 2, 3, and 6 is 1. The numbers are relatively prime.
