Coprime integers

Coprime integers are two whole numbers that share no common positive factors other than 1. In simpler terms, their greatest common divisor (GCD) is 1, meaning they cannot be evenly divided by any other number except 1. For example, 8 and 15 are coprime because no number besides 1 divides both evenly. This concept is important in number theory and has applications in fractions, cryptography, and algorithms. Being coprime indicates a kind of mathematical independence, showing that the two numbers are structurally unrelated in terms of their divisibility.
