What are the rules for dividing each number from 1 to 10

77julia77 [94]

Any integer (not a fraction) is divisible by 1

The sum of the digits is divisible by 3

The last 2 digits are divisible by 4

The last digit is 0 or 5

Is even and is divisible by 3 (it passes both the 2 rule and 3 rule above)

Double the last digit and subtract it from a number made by the other digits. The result must be divisible by 7. (We can apply this rule to that answer again)

The last three digits are divisible by 8

The sum of the digits is divisible by 9

The number ends in 0

Add and subtract digits in an alternating pattern (add digit, subtract next digit, add next digit, etc). Then check if that answer is divisible by 11.
