Question

Using divisibility rules, determine which of the following numbers are divisible by 2.
(a) 2144
(b) 1258
(c) 633
(d) 1352

Answer 1

If the unit digit of a number is 0, 2, 4, 6 or 8, then it is exactly divisible by 2.
(a) In 2144, the unit digit is 4, so it is divisible by 2.
(b) In 1258, the unit digit is 8, so it is divisible by 2.
(c) In 633, the unit digit is 3, so it is NOT divisible by 2. (d) In 1352, the unit’s digit is 2, so it is divisible by 2.

Hence, among the given options, 2144, 1258 and 1352 are divisible by 2 and 633 is not divisible by 2.
