Check the sum of the digits, if the sum divisible by 3 then the number is divisible by 3. Example 910: the sum of digits= 9 + 1 + 0 = 10, but 10 is not divisible by 3, so the number 910 is not divisible by 3. Example 2154: the sum of digits = 2 + 1 + 5 + 4 = 12, this sum is divisible by 3, so the number 2154 is divisible by 3. if the sum is long you can check the sum of the sum and apply the same rule. Example 52498731: the sum of digits = 5 + 2 + 4 + 9 + 8 + 7 + 3 + 1 = 39, the sum of the digits for 39 = 3 + 9 = 12, so the original number, i.e. 52498731 is divisible by 3.

Is 8435 divisible by 3?
To determine if a number is divisible by 3, add all the digits. If the sum is divisible by 3, so is the number. 8+4+3+5 = 20, which is not divisible by 3 (not a multiple of 3). So, 8435 is not divisible by 3.
What is a quick way to determine if 3 is a factor of a number?
If the sum of the digits of a given number is divisible by three, the number is divisible by three.
Is 313 or 351 equally divisible by 3?
To determine if a number is divisible by 3, you can add up the digits of the number and check if the sum is divisible by 3. For 313, the sum of the digits is 3+1+3=7, which is not divisible by 3. For 351, the sum of the digits is 3+5+1=9, which is divisible by 3. Therefore, 351 is divisible by 3, but 313 is not.
What is the rule to determine if a number is divisible by 12?
That the number is divisible by 4* and the sum of its digits is a multiple of 3. *If the number has three of more digits then it is only necessary to look at the tens and units to determine if it is divisible by 4, as 4 is a factor of 100 and therefore of any multiple of 100. Examples : 75 : is not divisible by 4 although its digits total 12 which is a multiple of 3. 132 : is divisible by 4 as 32 is divisible by 4, and its digits total 6 which is divisible by 3, then 132 is divisible by 12.
Write a rule to determine when a number is divisible by 12?
A number is divisible by 12 if it is divisible by 3 AND it is divisible by 4. Rule 1a (Divisibility by 3): Add up all the digits of the number. Is this number divisible by 3? Rule 1b (Divisibility by 4): Is the number formed by the last two digits of the original number (the number left after deleting the hundreds, thousands, millions etc) divisible by 4? If the answer to 1a is NO, then the number is not divisible by 3 and so not divisible by 12. In this case, obviously, rule 1b is irrelevant. If the answer to 1b is NO, then the number is not divisible by 4 and so not divisible by 12. If the answer to both 1a and 1b is YES, then the number is divisible by 12.
How do you know if 54132 is divisible by 6?
To determine if a number is divisible by 6, it must be divisible by both 2 and 3. To determine if a number is divisible by 2, it should be even - in other words, it should end with 0, 2, 4, 6, or 8. To determine if a number is divisible by 3, the sum of its digits should be divisible by 3. 54,132 is an even number, so it is divisible by 2. 5 + 4 + 1 + 3 + 2 = 15, which is divisible by 3, so 54,132 is divisible by 3. Since 54,132 is divisible by both 2 and 3, it is divisible by 6.
Is 8435 divisible by 3?
To determine if a number is divisible by 3, add all the digits. If the sum is divisible by 3, so is the number. 8+4+3+5 = 20, which is not divisible by 3 (not a multiple of 3). So, 8435 is not divisible by 3.
What is a quick way to determine if 3 is a factor of a number?
If the sum of the digits of a given number is divisible by three, the number is divisible by three.
Is 7960 a divisible by 3?
To determine if a number is divisible by 3, you need to add up its individual digits. In this case, 7 + 9 + 6 + 0 = 22. Since 22 is not divisible by 3 (it does not result in a whole number), 7960 is not divisible by 3.
Is 1218 divisible by 3?
Yes, it is. Your answer is 406. You can determine whether a number is divisible by 3 by adding the digits. If the sum of the digits (in the above, 1+2+1+8 = 12) equals 3, the number is divisible by 3.
Is 7902 divisible by 3?
Yes. An easy way to determine if a number is divisible by 3: Sum the digits of the number: 7+9+0+2 = 18. If that sum is divisible by 3 then the number is also. As you can see the sum is 18, so 7902 is divisible by 3. 7902/3 = 2634
Is 313 or 351 equally divisible by 3?
To determine if a number is divisible by 3, you can add up the digits of the number and check if the sum is divisible by 3. For 313, the sum of the digits is 3+1+3=7, which is not divisible by 3. For 351, the sum of the digits is 3+5+1=9, which is divisible by 3. Therefore, 351 is divisible by 3, but 313 is not.
How do you determine whether a number is divisible by three?
you add the numbers together and if that is divisible by three then so is that number for example: the number 111, you would do 1+1+1=3 so 111 is dividable by 3; or the number 1,620, 1+6+2+0= 9 (which is divisible by 3) so 1,620 is divisible by 3

Is there a number divisible by 6. But not 3?
yeah3 9 15 21 27 and so on(every other multiple of three)But if you have a large number, like 755253, and don't have a calculator handy, then use sum of digits to determine if divisible by 3.Then if the number is divisible by 3 and divisible by 2, then it is also divisible by 6.So in this case: 7 + 5 + 5 + 2 + 5 + 3 = 27, which is divisible by 3, but the original number is odd, so the number is not divisible by 6.
What number make 371 divisible by 3?
To determine what number makes 371 divisible by 3, we need to sum the digits of 371: 3 + 7 + 1 = 11. To be divisible by 3, the sum of the digits must also be divisible by 3. Since 11 is not divisible by 3, we need to find the number that, when added to 11, results in a sum divisible by 3. The next multiple of 3 greater than 11 is 12, so the number that makes 371 divisible by 3 is 1.
