Two numbers are relatively prime if the only factor they have in common is 1. Example: 12 and 17 are relatively prime because they have only 1 as a common factor. 12 and 21 are not relatively prime because they have 1 and 3 as common factors.
Two numbers are relatively prime if the only factor they have in common is 1. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 25 are 1, 5, and 10. The only factor they have in common is 1, so they are relatively prime.
