Best Answer

By 3 only.

It is not divisible by 2, 4, 5, 6, 9 & 10.

Division tests:

- 2:

633 is odd (last digit is 3 which is not an even digit), so 633 is not divisible by 2.

- 3:

(Can repeat the summing until a single digit remains; if this digit is 3, 6 or 9 (ie divisible by 3) then the original number is divisible by 3.)

6 + 6 + 3 = 15

1 + 5 = 6

6 is divisible by 3, so 663 is divisible by 3.

- 4:

(Can repeat summing until a single digit remains; if this digit is 4 or 8 (ie divisible by 4) then the original number is divisible by 4.)

6 x 2 + 3 = 15

1 x 2 + 5 = 7

7 is not divisible by 4, so 663 is not divisible by 4.

Note: all multiples of 4 are even; 633 is odd so it cannot be divisible by 4 (the above test does not need to be done).

- 5:

3 is not 0 nor 5, so 663 is not divisible by 5.

- 6:

Fails 2 test (above), so 663 is not divisible by 6.

- 9:

(Can repeat the summing until a single digit remains; if this digit is 9 (ie divisible by 9) then the original number is divisible by 9)

6 + 6 + 3 = 15

1 + 5 = 6

6 is not 9, so 663 is not divisible by 9.

- 10:

3 is not 0, so 663 is not divisible by10.
