A factor is a number that divides another number completely without remainder. Factors can be positive or negative, but commonly only positive ones are used. Every number except 0 and 1 has at least two factors: 1 and itself. The number of factors of a number is finite
Finds greatest common divisor (GCD) of two positive integers. Divides a by b, keeping remainder until it becomes zero. If a<b, exchanges them. Algorithm stops when remainder decreases by at least 1
A factor is a number that divides another number without leaving a remainder. Only positive integers can be considered as factors. The smallest factor of any number is 1, and the largest is the number itself. Every integer has at least two factors: 1 and itself
