Divide test calculator
If the quotient of integer a divided by non-zero integer b is an integer and the remainder is zero, we say that a can be divided by b (or b can divide a), denoted as b | a. Note that if b is 0, it is not called division.
The property of division: (1) If a can be divided by b and c is any integer, then the product ac can also be divided by b; (2) If a is divided by both b and c, and b and c are coprime, then a must be divided by the product bc, and vice versa.
