I hope This Answers your Question

Step-by-step explanation:

A number is divisible by 2 if the digit at unit place is either 0 or multiple of 2.

So a number is divisible by 2 if digit at its units place is 0, 2, 4, 6 or 8.

Numbers divisible by 2 are called even numbers.

Numbers not divisible by 2 are called odd numbers.

Let us consider some of the following numbers which are divisible by 2 using the divisibility test.

346, 218, 106, 100, 194, 152 here all these number is divisible by 2 because their units place is either 0 or multiple of 2.

Similarly, the numbers 14, 64, 86, 102, 568, 120 etc. is divisible by 2 because their units place is either 0 or multiple of 2.

Similarly again, 182, 198, 200, 100, 406, 304 are also divisible by 2 because their units place is either 0 or multiple of 2.Again let us consider,

317, 125, 103, 159 etc. here all these number is not divisible by 2 because their units place is not multiple of 2.
