To find out whether a no. is divisible by 7, we must: a) separate the units place: eg. 84 = 8 4 b) then double the no. in units place 4 x 2 = 8 c) subtract it from the no. formed by the remaining digits 8- 8 = 0 Then if the obtained no. is divisible by 7 (0= 7x0) , then the original no. is also divisible. ( 12 x 7 = 84 )

What is the divisibility test for 7?
You can determine if a number is divisible by 7 by using the following method: E.g. 161 - Double the last digit (2 x 1 = 2) Subtract 2 from the number formed by the the remaining digits in this case, 16 -2 = 14 If the result is divisible by 7 (14 /7 =2); then the original number is divisible by 7. 161 / 7 = 23

What is the number theory for figurng out what is divisible by 7?
First of all, it is the one that is probably not even worth doing. It is honestly easier in most cases to just try it! To determine if a number is divisible by 7, take the last digit off the number, double it and subtract the doubled number from the remaining number. If the result is evenly divisible by 7 (e.g. 14, 7, 0, -7, etc.), then the number is divisible by seven. This may need to be repeated several times.
