Understand why

↗

In the Euclidean algorithm, when the division process yields a remainder of zero, the greatest common divisor of the original two integers is the last non-zero remainder obtained. The algorithm stops at this point because the method is over, and the last non-zero remainder is guaranteed to divide both original numbers evenly.

Conditions: The Euclidean algorithm is applied to two integers.; The process of repeated long division is followed until a remainder of zero is reached.

To compute the greatest common divisor of 1785 and 546, apply the Euclidean algorithm by repeatedly dividing the previous divisor by the previous remainder. Start with 1785 divided by 546.

Conditions: The inputs are 1785 and 546.; The Euclidean algorithm is used.; The division algorithm is applied at each step.

The Euclidean algorithm finds the greatest common divisor (GCD) of two integers without needing to factor them. The process involves repeatedly performing long division: divide the larger number by the smaller number, then divide the previous divisor by the remainder, and continue this process.

Conditions: Applies to two integers.; Requires repeated long division.; Stops when the remainder is zero.
