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 677 and 952?
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 | 677 ÷ 952 = 0 remainder 677 |
| 2 | 952 ÷ 677 = 1 remainder 275 |
| 3 | 677 ÷ 275 = 2 remainder 127 |
| 4 | 275 ÷ 127 = 2 remainder 21 |
| 5 | 127 ÷ 21 = 6 remainder 1 |
| 6 | 21 ÷ 1 = 21 remainder 0 |
