Question

The number 2 is a factor of _________.

Answer 1

hello!

2 is a factor of all even numbers (numbers that end with 2, 4, 6, 8, 0)

Option A) is wrong because 1, 3, 5, 7, 9 & numbers that end with the digits listed above are not evenly divisible by 2; this is the reason why Option C) is wrong.

In order for a digit/number to be a factor of a number, it should be evenly divisible by that number.
