WebDivisibility. Definition. If a and b are integers, then a divides b if for some integer n. In this case, a is a factor or a divisor of b. The notation means "a divides b". The notation means a does not divide b. Notice that divisibility is defined in terms of multiplication --- there is no mention of a "division" operation.
