Yes. An easy way to see if any number can be divided by 3, is to add up the digits in the number. If the digits in the number add up to a multiple of three, it is divisible by 3. 261 --> 2 + 6 + 1 = 9 (9 is divisible by 3, so in turn 261 is also) 210 --> 2 + 1 + 0 = 3 (3 can be divided by itself, so 210 is divisible by 3) 8349 --> 8 + 3 + 4 + 9 = 24 (24/3=8, so 8349 is divisible by 3)
