Answers to Questions
What are coprimes? (Definition)
Prime numbers between them are numbers that share no common divisor (except 1).
How to calculate if numbers are coprimes?
Two numbers are coprimes if the GCD (greatest common divisor) of these numbers is equal to 1. This definition can be extended to N numbers.
Example: GCD(4,6) = 2, then 4 and 6 are not coprimes.
Example: GCD (4,5,6) = 1 then 4, 5 and 6 are coprimes (even if 4 and 6 are not).
Example: GCD (7,12) = 1 then 7 and 12 are coprimes.
How to find a coprime number with another?
dCode tests numbers depending on the prime factor decomposition of the first number (and therefore its divisors) to find coprime numbers. Then check that GCD equals 1 to confirm the number.
