Muhammad Baqir Yazdi Persian: محمدباقر یزدی was an Iranian mathematician who lived in the 16th century. He gave the pair of amicable numbers 9,363,584 and 9,437,056 many years before Euler's contribution to amicable numbers.[1] His major book is Oyoun Alhesab (Arabic:عيون الحساب).
Works
- Oyoun al-Hisab: Yazdi's principal mathematical text is Oyoun al-Hisab (Arabic: عيون الحساب), known as The Sources of Arithmetic. It represents a late Islamic scholarly attempt to systematize arithmetic, geometry, and algebra inherited from earlier traditions.[2][3]
Contributions to number theory
Yazdi identified the Amicable numbers (9,363,584; 9,437,056), which he derived using the classic formula of Thābit ibn Qurra for 𝑛 = 7. Though often attributed to Descartes or Fermat, this pair was first recorded by Yazdi.[4][5][6]
