yes, because 861 divided by 3 is 287
No.
861 is divisible evenly by 3 but none of the others
1, 3, 7, 9, 21, 41, 63, 123, 287, 369, 861, 2583.
It is divisible by three which gives you 247
77922 is divisible by 6. 77922 / 6 = 12987 To check if a number is divisible by 6, the number has to be even and divisible by three. An easy way to check if a number is divisible by three is to see if the sum of the digits is divisible by three. 77922 7+7+9+2+2 =27 27 2+7 =9 9 is divisible by three, so 77922 is divisible by three also.
No.
861 is divisible evenly by 3 but none of the others
1, 3, 7, 9, 21, 41, 63, 123, 287, 369, 861, 2583.
By the multiples of 123 (which are infinite), including these: 123, 246, 369, 492, 615, 738, 861, 984, 1107 . . .
No. If a number is divisible by three, the sum of its digits will be divisible by three. Obviously, the sum of the digits of 10000 is 1, and 1 is not divisible by 3, so 10000 is not divisible by 3.
No. 3,364 is not divisible by three.
No, it is not divisible by three.
No, 3637 is not divisible by three.
It is divisible by three which gives you 247
211 is not divisible by three.
Add the digits. If the total is divisible by three, the original number is divisible by three. It's not and it's not.
If all the digits in a number add up to a number divisible by three, the number itself is divisible by three.For example the number 711: 7 + 1 + 1 = 9. Nine is divisible by three, therefore 711 is divisible by three.
