Test 275 for Divisibility by 3

Test for Divisibility by 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 275: 2+7+5 = 14
14 is not divisible by 3
Therefore, 275 is NOT divisible by 3
Note: Since 275 is not divisible by 3, it follows that 275 is also not divisible by any multiple of 3 (6, 9, 12, …)
