What is Divisibility Rule of 8

In this video, we explore the Divisibility Rule of 8, a simple yet effective method for determining whether a number is divisible by 8. According to this rule, a number is divisible by 8 if the number formed by its last three digits is divisible by 8. For example, if the last three digits of a number are 232, and 232 is divisible by 8, then the entire number is divisible by 8. This rule significantly simplifies divisibility checks, especially for large numbers, allowing for faster calculations without the need for long division.

The Divisibility Rule of 8 is an essential tool in number theory and is particularly useful in tasks like simplifying fractions and prime factorization. It is also commonly applied in mathematical puzzles and exams, helping solve problems quickly and efficiently. Mastering this rule not only speeds up mathematical operations but also lays the foundation for more advanced concepts in divisibility, factorization, and modular arithmetic.
