Answers to Questions

How to calculate if numbers are coprimes?

Two numbers are said to be coprime if the GCDhref (greatest common divisor) of these numbers is equal to 1. This definition can be extended to N numbers.

GCD(4,6) = 2, then 4 and 6 are not coprimes.

GCDhref (4,5,6) = 1 then 4, 5 and 6 are coprimes (even if 4 and 6 are not).

GCDhref (7,12) = 1 then 7 and 12 are coprimes.

How to find a coprime number with another?

dCode tests numbers depending on the prime factorhref decomposition of the first number (and therefore its divisorshref) to find coprime numbers. Then simply check that GCDhref equals 1 to confirm the number.
