Examples of co prime numbers
WebCo-Prime Definition: Co-prime numbers are different from prime numbers. Two numbers are called co-prime numbers if and only if they have 1 as their common factor. This can be demonstrated with an example: Let us take two numbers, say 16 and 17; if we factorize each number, we get: 16 = 1 x 2 x 2 x 2 x 2, or 1 x 4 x 4, or 1 x 2 x 8. WebFor example, 4 and 5 are co-prime numbers. Here, 5 + 4 = 9 is coprime with 4 × 5 = 20. ...

For example, $2$ & $3$ and … A set of integers can also be called coprime or setwise coprime if the greatest common divisor of all the elements of the set is 1. For example, the integers 6, 10, 15 are coprime because 1 is the only positive integer that divides all of them. If every pair in a set of integers is coprime, then the set is said to be pairwise coprime (or pairwise relatively prime, mutually coprime or mutually relatively prime).
