Two numbers are relatively prime if they have no factors in common other than 1. This means their greatest common factor (GCF) is 1. Here are examples of pairs of numbers that are relatively prime: 2, 9
5, 14
13, 998
3, 379
37, 303
691, 701
32, 81
384, 625 Here are examples of pairs of numbers that are not relatively prime: 2, 8 (GCF: 2)
16, 1060 (GCF: 4)
52, 117 (GCF: 13)

What two numbers have 1 as there gcf?
Prime and relatively prime numbers all have a GCF of 1.
Are two consecutive numbers always relatively prime?
Yes.
Is 45 and 64 relatively prime?
Numbers are either prime or they aren't. In this case, 45 is divisible by 3 and 15; sixty-four goes into 2, 4, 8 and 32. The term "relatively prime" compares two numbers and their common factors. If the GCF of the two numbers is 1, then they are "relatively prime."
What does 'relatively prime' mean?
'Relatively Prime' simply means that two numbers have no common factors except 1 between each other. For example, two prime numbers would have no common factors between them. i.e., look at 3 and 10. There are no common factors between these 2 numbers.
If two numbers only share a factor of 1 what is it called?
Co-prime or relatively prime
