It can be. 50 is relatively prime to 51.
No, 50 and 65 are not relatively prime.
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.
No they are not.
14 is relatively prime with the two given numbers.
Yes.
A single number cannot be relatively prime. Any pair of numbers between 50 and 100 of which one is a prime will be relatively prime. There are 728 pairs of numbers that are relatively prime and I have neither the time nor patience to list them all!
All of them. Any number greater than one can be relatively prime.
1 It is a relatively prime number.
No, both are divisible by 25.
20 numbers from 1 to 50 are relatively prime with 50. They are 1, 3, 7, 9, 11, 13, 17, 19, 21, 23, 27, 29, 31, 33, 37, 39, 41, 43, 47 and 49. The only factor any of those share with 50 is 1, making them relatively prime with 50.
No, they are not relatively prime.
It can be. 34 is relatively prime to 35. 34 is not relatively prime to 40.
