SUMMARY
The discussion focuses on proving that if \( d = \text{gcd}(a, b) \), then \( \text{gcd}\left(\frac{a}{d}, \frac{b}{d}\right) = 1 \). The key insight is that demonstrating 1 as a linear combination of \( \frac{a}{d} \) and \( \frac{b}{d} \) is essential to establish their coprimality. The approach involves recognizing that dividing both \( a \) and \( b \) by their greatest common divisor \( d \) simplifies the problem to showing that the resulting integers share no common factors other than 1.
