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 92 and 124?
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 | 92 ÷ 124 = 0 remainder 92 |
| 2 | 124 ÷ 92 = 1 remainder 32 |
| 3 | 92 ÷ 32 = 2 remainder 28 |
| 4 | 32 ÷ 28 = 1 remainder 4 |
| 5 | 28 ÷ 4 = 7 remainder 0 |
