What is the Greatest Common Divisor (GCD)?
The GCD of two integers is the largest positive integer that divides both numbers without leaving a remainder. It is useful in simplifying fractions, finding common factors, and in number theory.
How to Calculate the GCD of 96 and 173?
We use the Euclidean algorithm, which involves the following steps:
- Divide the larger number by the smaller number.
- Replace the larger number with the smaller number and the smaller number with the remainder from the division.
- Repeat this process until the remainder is zero.
- The non-zero remainder just before zero is the GCD.
Step-by-Step Euclidean Algorithm
| Step | Calculation |
|---|---|
| 1 | 96 ÷ 173 = 0 remainder 96 |
| 2 | 173 ÷ 96 = 1 remainder 77 |
| 3 | 96 ÷ 77 = 1 remainder 19 |
| 4 | 77 ÷ 19 = 4 remainder 1 |
| 5 | 19 ÷ 1 = 19 remainder 0 |
