The congruent number descent of Komotu, Watanabe and Wada
英文摘要：
We present an elementary exposition of the descent method used by Komoto, Watanabe and Wada to show $N=42553$ is a congruent number. We generalize to $N=7p$ with $p$ prime, and try to present the method such that an amateur could understand and perform their own calculations.
