- If \(a=kd\), then \(d\) and \(k\) both divide \(a\).
- The definition regards a property of a pair of integers (where order matters).
- 6 divides 12. 2 and 3 both divide 6. 2 and 3 both divide 12. 12 divides 60. 2, 3, 4, 5, and 6 all divide 60. 5 does not divide 12. 7 does not divide 60. 6 does not divide 3.
