Test for Divisibility by 3:
• A Number is divisible by 3 if the Sum of the Digits in the Number is divisible by 3
Sum of the Digits in 22: 2+2 = 4
4 is not divisible by 3
Therefore, 22 is NOT divisible by 3
Note: Since 22 is not divisible by 3, it follows that 22 is also not divisible by any multiple of 3 (6, 9, 12, …)
