Given Number: 2,799,588
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 2,799,588: 2+7+9+9+5+8+8 = 48
48 is not divisible by 9
Therefore, 2,799,588 is NOT divisible by 9
Note: Since 2,799,588 is not divisible by 9, it follows that 2,799,588 is also not divisible by any multiple of 9 (18, 27, 36, …)
