Revisiting Fermats Little Theorem Modular Properties of Composite Numbers with Two Prime Factors
Fermat's Little Theorem is a cornerstone of number theory, asserting that for prime numbers, raised to the power of a prime number minus one, the result is congruent to 1 modulo the prime. This theorem has profound implications in various fields, particularly cryptography. However, recent investigations have unveiled a nuanced extension of this theorem, contradicting its original scope. We present a thorough analysis of composite numbers possessing precisely two prime factors, revealing unexpected modular properties that challenge Fermat's original assertion. Through rigorous mathematical reasoning and modular arithmetic, we establish that these composite numbers exhibit distinctive congruence patterns, shedding new light on their structural characteristics. Our findings not only extend the applicability of Fermat's Little Theorem but also offer novel insights into the modular behavior of composite numbers with biprime factors. The significance of this finding is that Fermat’s Little Theorem can be extended to composite numbers.
