Test 16 for Divisibility by 3

Given Number: 16
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 16: 1+6 = 7
7 is not divisible by 3
Therefore, 16 is NOT divisible by 3
Note: Since 16 is not divisible by 3, it follows that 16 is also not divisible by any multiple of 3 (6, 9, 12, …)

The solution above and all other related solutions were provided by the Test for Divisibility by 3 Application.
