Given Number: 422
Test a Number for Divisibility by Three (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 422: 4+2+2 = 8
8 is not divisible by 3
Therefore, 422 is NOT divisible by 3
Note: Since 422 is not divisible by 3, it follows that 422 is also not divisible by any multiple of 3 (6, 9, 12, …)
