Modular Multiplication without Trial Division

. Mathematics of Computation, 44 (170): 519--521 (1985)

Abstract

Let N>1. We present a method for multiplying two integers (called N-residues) modulo N while avoiding division by N. N-residues are represented in a nonstandard way, so this method is useful only if several computations are done modulo one N. The addition and subtraction algorithms are unchanged.
