Answer» ility RULES (2,3,5,7,11,13,17,19,...)A divisibility rule is a heuristic for determining whether a positive integer can be evenly divided by another (i.e. there is no remainder left over). For example, determining if a number is even is as SIMPLE as checking to see if its last digit is 2, 4, 6, 8 or 0. Multiple divisibility rules APPLIED to the same number in this way can help quickly determine its prime factorization |
