When is a Number Divisible by 2?
There are times when these divisibility rules can be helpful in simplifying numbers and prime factorization, and times when these rules can be helpful in determining whether a number is a multiple of another number. A number is divisible by 2 if the ones digit is 0, 2, 4, 6, or 8 – that is, if the units digit is even. For example, 30, 42, 54, 66, and 78 are divisible by 2.
