🔢 Number theory fact
The Strength of Relative Primality
Two integers are considered coprime if the only positive integer that divides both of them is 1. This means they share no common factors, making them 'mathematically independent' in terms of divisibility. This concept is a cornerstone of modern cryptography, helping to keep our digital communications secure.
