Number Theory: Divisibility
Test your knowledge of divisibility — the rules and relationships that describe how integers divide into each other evenly.
Questions cover divisibility rules for common numbers, finding the greatest common divisor and least common multiple, and the Euclidean algorithm.
These shortcuts save real time on arithmetic — see how many you actually use.
