Answer 2

Hey there!

$\textbf {Divisibility of 2 }$

Any number is divisible by 2, if it's an even number. Every Even number is divisible by 2.

E.g.: 4 is divisible by 2 'cause it's an even number.

$\textbf {Divisibility of 3 }$

Add the digits of the number. If sum of digits of number is divisible by 3, then the whole number is divisible by 3.

E.g.: 234 is divisible by 3
2+3+4 = 9, which is a factor of 3.
So, 234 is divisible by 3.

Hope helped.
