Given Number: 8,142
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 8,142: 8+1+4+2 = 15
15 is not divisible by 9
Therefore, 8,142 is NOT divisible by 9
Note: Since 8,142 is not divisible by 9, it follows that 8,142 is also not divisible by any multiple of 9 (18, 27, 36, …)
