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 133 and 183?
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 | 133 ÷ 183 = 0 remainder 133 |
2 | 183 ÷ 133 = 1 remainder 50 |
3 | 133 ÷ 50 = 2 remainder 33 |
4 | 50 ÷ 33 = 1 remainder 17 |
5 | 33 ÷ 17 = 1 remainder 16 |
6 | 17 ÷ 16 = 1 remainder 1 |
7 | 16 ÷ 1 = 16 remainder 0 |
