For a number to be divisible by 105 it must be divisible by 3, by 5 and by 7. So, divisibility by 3 requires all three of the following to be satisfied:
- Sum the digits together. Repeat if necessary. If the answer is 0, 3, 6 or 9 the original number is divisible by 3.
- If the final digit of the number is 0 or 5, the original number is divisible by 5.
- Take the number formed by all but the last digit. From it subtract double the last digit. Keep going until there is only one digit left. If it is 0 or 7 then the original number is divisible by 7.
a number can be divided by 2 evenly only if the number ends in the following numbers...0, 2, 4, 6, 8
a number can be divided by 3 evenly only if the sum of all the digits in the number is divisible by 3
a number can be divided by 4 if the numbers last two digits are divisible by 4
a number can be divided by 5 only if the number ends in the following... 0, 5
a number can be divided by 6 only if the number is divisible by two and three
a number can be divide by 7 only if the number can be divided by 7 (no way for 7)
a number can be divided by 8 only if the last two digits of the number is divisible by 8
a number can be divided by 9 only if the sum of all the digits in the number is divisible by 9
a number can be divided by ten only if it ends with the number zero
