Question

Using divisibility tests, determine which of following numbers are divisible by $2$
$\left(a\right)2144\left(b\right)1258\left(c\right)4336\left(d\right)633\left(e\right)1352$

Answer 1

A number is $divisible$ by $2$ if the last digit is $0,2,4,6$ or $8.$
So, $2144,1258,4336,1352$ are divisible by $2$ and $633$ is not divisible by $2$.
