Given Number: 479,623
Test a Number for Divisibility by Nine (9):
• A Number is divisible by 9 if the Sum of the Digits in the Number is divisible by 9
Sum of the Digits in 479,623: 4+7+9+6+2+3 = 31
31 is not divisible by 9
Therefore, 479,623 is NOT divisible by 9
Note: Since 479,623 is not divisible by 9, it follows that 479,623 is also not divisible by any multiple of 9 (18, 27, 36, …)
