First multiply the rightmost unit digit by 2 and then subtract the product from the remaining digits. Is 623 divisible by 7. Divisbility Rule of 7.

A number of the form 10a b is divisible by 7 if and only if a 2b is divisible by 7. If the difference is divisible by 7 then the original number must also be divisible by 7. The result is either 0 or divisible by 7.

The unit digit of 798 is 8. In other words subtract twice the last digit from the number formed by the remaining digits. Since 63 is divisible by 7.

The sum of the last digit and 3 times the rest is a multiple of 7 The sum of 3 times the last digit and twice the rest is a multiple of 7. First take the last digit of the number and double it. The absolute difference between twice the units digit and the number formed by the rest of the digits must be divisible by 7 7 7 this process can be repeated for many times until we arrive at a sufficiently small number.

From the rule stated remove 3 from the number and double it which becomes 6. Take the digits of the number backward from right to left multiplying them progressively by the digits 1 3 2 6 4 5 repeating with this pattern of multipliers as long as necessary. The divisibility rule of 7 states that for a number to be divisible by 7 the last digit of the given number should be multiplied by 2 and then subtracted with the rest of the number leaving the last digit.

6 rows The divisibility rule of 7 states that for a number to be divisible by 7 the last digit of the. Remaining number becomes 107 so 107-6 101. Proof An understanding of basic modular arithmetic is necessary for this proof.

Continue to do this until a small number. Since the last digit of 65973390 is 0 hence it is divisible by 5. The divisibility rule of 7 states that if a number is divisible by 7 then the difference between twice the unit digit of the given number and the remaining part of the given number should be a multiple of 7 or it should be equal to 0.
