How do you know if a number is relatively prime?

Therefore, the easiest way to determine if two numbers are relatively prime is to factor each number into its prime factorization and see if any factors are in common. If not, then the numbers will be relatively prime.

What is an example of relatively prime?

Two numbers are said to be relatively prime if their greatest common factor ( GCF ) is 1 . Example 1: The factors of 20 are 1,2,4,5,10, and 20 . The factors of 33 are 1,3,11, and 33 .

Which number is relatively prime to 63?

Another way to state that a set of numbers are relatively prime is to say that they are coprime. Consider the numbers 20 and 63. Since the greatest common factor of 20 and 63 is 1, 20 and 63 are relatively prime.

What numbers are relatively prime to 16?

There are 5 factors of 16, which are 1, 2, 4, 8, and 16. Here, 16 is the biggest factor. The Prime Factors of 16 are 1, 2, 4, 8, 16 and its Factors in Pairs are (1, 16), (2, 8), and (4, 4).

What number is relatively prime 17?

For example, 17 and 25 are relatively prime because the common factor of both numbers is 1. Factors of 17 are 1 and 17 and factors of 25 are 1, 5, 25.

What numbers are relatively prime with 15?

There are 8 positive integers less than 15 and co- prime with 15. They are 1, 2, 4, 7, 8, 11, 13 and 14.

What is pairwise relatively prime?

A list of integers is pairwise relatively prime if every pair of the items in the list are relatively prime. If two integers have greatest common divisor one, then they are pairwise relatively prime (since there is only one pair). …

What number is relatively prime to 242?
