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 150 and 112?
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 | 150 ÷ 112 = 1 remainder 38 |
| 2 | 112 ÷ 38 = 2 remainder 36 |
| 3 | 38 ÷ 36 = 1 remainder 2 |
| 4 | 36 ÷ 2 = 18 remainder 0 |
