Given Number: 5,280
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 5,280: 5+2+8+0 = 15
15 is not divisible by 9
Therefore, 5,280 is NOT divisible by 9
Note: Since 5,280 is not divisible by 9, it follows that 5,280 is also not divisible by any multiple of 9 (18, 27, 36, …)
