In 1742, firstly Leonhard Euler invented the generating function for *P*(n), where *P*(n) is the number of partitions of n [*P*(n) is defined to be 1]. Srinivasa Ramanujan was born on 22 December 1887. In 1916, S. Ramanujan invented the generating function for *P*(n) (2^{nd} time). Godfrey Harold Hardy said Srinivasa Ramanujan was the first, and up to now the only, Mathematician to discover any such properties of *P*(n). MacMahon established a table of *P*(n) for the first 200 values of n, and Ramanujan observed that the table indicated certain simple congruences properties of *P*(n). In 1916, S. Ramanujan quoted his famous partition congrucnecs. In particular, the numbers of the partitions of numbers 5m+4, 7m+5, and 11m+6 are divisible by 5, 7, and 11 respectively. Now this paper shows how to prove the Ramanujan’s famous partitions congruences modulo 5, 7, and 11 respectively.
