Take each digit of the number in reverse order , multiplying them successively by the digits 1 , 3 , 2 , 6 , 4 , 5 , repeating with this sequence of multipliers as long as necessary 1, 3, 2, 6, 4, 5, 1, 3, 2, 6, 4, 5, Retrieved If the end result is zero or a multiple of seven, then yes, the number is divisible by seven. If the integer is between 1, and one million, find a repeating pattern of 1, 2, or 3 digits that forms a 6-digit number that is close to the integer leading zeros are allowed and can help you visualize the pattern. If the last number is either 0 or 5, the entire number is divisible by 5. Adding the last two digits to twice the rest gives a multiple of 7.
