What is the divisibility rule of 7?

The divisibility rule of 7 is, consider any number say 651, then take its once place number that is 1 double it, it becomes

2. subtract the doubled number 2 with the rest number, i.e., 65-2=63, as resultant number 63 is divisible by 7, we can say that 651 is divisible by 7. statement is: take the once digit number double it and doubled number must be subtracted with the rest number. And what result you will get if it is divisible by 7 then the given number is considered as divisible by 7.

Divisibility rules are the method which tells if the particular number is divisible by any other number or not. 7 is divisible by taking the last digit of the number, doubling it and then subtracting the doubled number from the remaining number. If the number is evenly divisible by seven, the number is divisible by seven.
