Q: Is 7 divisible by 3?

Write your answer...

NO. 313 is not divisible by 3.A number is divisible by 3 if the sum of the digits is divisible by 3.313 = 3 + 1 + 3 = 7Note: 7 not divisible by 3 thus, 313 is not divisible by 3.

3*21 = 63 so 63 is divisible by 3 7*9 = 63 so 63 is divisible by 7.

33 divisible by 3. 14 divisible by 7. 4 divisible by both. Total: 43

a number is divisible by 12 if the number is also divisible by both 3 and 7. You mean a number is divisible by 21 if it is divisible by 3 and 7.

Because 21 is a multiple of 1, 3, 7 and 21.

The smallest number that can be divisible by these three numbers is 42. If 42 is multiplied by 2, 3, 7, or any number divisible by only one of those numbers then that number as well will be divisible by 2, 3, and 7.

18444 is divisible by 3: 18444/3 = 6148. 18444 is not divisible by 5: 18444/5 = 3688.8 18444 is divisible by 6: 18444/6 = 3074 18444 is not divisible by 7: 18444/7 = 2634.857142 18444 is not divisible by 10: 18444/10 = 1844.4

No; 1+7+3+5= 16 16 isn't divisible by 3.

19 divisible by 5, 14 divisible by 7. Of these, 3 divisible by both.

1, 2, 7, 3 and 6 are not divisible by 4 and/or 9. 12736 is divisible by 4 but not by 9.

if one of its factors are a 3 or after dividing a number by 3, their are no remainders There is also another trick: add all of the digits of the number together. The original number is divisible by 3 if and only if the sum of the digits is divisible by 3. For example: 321 is divisible by 3 because 3+2+1=6 and 6 is divisible by 3. 322 is not divisible by 3 because 3+2+2=7 and 7 is not divisible by 3.

A number is divisible by 6 if it is divisible both by 2 and 3 1240 is even then is divisible by 2 1+2+4+0 = 7 which is not divisible by 3 then 1240 is not divisible by 3 Thus 1240 is not divisible by 6

Yes 72/3 = 24. Also, you can add up the digits and see if that sum is divisible by 3 (7 + 2 = 9, which is divisible by 3, so 72 is divisible by 3)

1, 21, 3, 7 are divisible by 21 :)

42 is divisible by 2, 3, 6, & 7

YES.A number is divisible by 3 if the sum of its digits is divisible by 3.72342:= 7 + 2 + 3 + 4 + 2= 18 (18 is divisible by 3)Check: 72342 ÷ 3 = 24114 (no remainder)

Odd numbers are integers (whole numbers) that are not divisible by 2: 1, 3, 5, 7, ..., -1, -3, -5, -7...Odd numbers are integers (whole numbers) that are not divisible by 2: 1, 3, 5, 7, ..., -1, -3, -5, -7...Odd numbers are integers (whole numbers) that are not divisible by 2: 1, 3, 5, 7, ..., -1, -3, -5, -7...Odd numbers are integers (whole numbers) that are not divisible by 2: 1, 3, 5, 7, ..., -1, -3, -5, -7...

No. But 870 is divisible by 3 (because 8+7+0 = 15 -> 1 + 5 = 6 and 6 is divisible by 3). 870/3 = 290.

Yes. 702 is even and so divisible by 2 7 + 0 + 2 = 9 which is divisible by 3 702 is divisible by 2 & 3 and so is divisible by 6.

21

2463. The trick is that a number is divisible by 3 if and only if the sum of its digits is divisible by 3. 1+3+2+4 = 10 (not divisible by 3), while 2+4+6+3 = 15 (divisible by 3).

What. Yes if the sum of its individual digits is divisible by 3. For example 177 is disible by 3 because 1+7+7 is 15, is divisible by 3. If you didn't know 15 is divisible by 3, you surely know that 1+5 is. Notice 6.3 is divisible by 3 for the same reason. Divisible by 3 means without having a recurring 3 or 6 in the answer, or having a remainder 1/3 or 2/3

7 is not divisible by any of them.

The numeral '21' is evenly divisible by 21, 7, 3, and 1.

Add up the digits of the number. If the sum is divisible by 3, then the number itself is divisible by 3. Ex: Is 781 divisible by 3? 7+8+1=16 16 is not divisible by 3 so neither is 781 Is 903 divisible by 3? 9+0+3= 12 12 is divisible by 3 so 903 is divisible by 3
