Sursinh Parmar is a mathematics teacher from Saurashtra. A student’s question led him to discover a new method to number 8’s divisibility rule. His method uses 2 simple rules:
For example, to check the divisibility of 1,23,632 by 8
1,23,6 (32) = (8×4)
The last two digits must be a multiple of 4
8 & 6 are both even numbers
The multiplier & the digit in the hundredth’s place must both be ODDxODD or EVENxEVEN
1,23,632 is a multiple of eight

12,12,1 (16) =(4 x 4)
4 is even, 1 is odd
12,12,116 is not a multiple of 8
Parmar was recently given the ‘Innovative Teacher’ award by the Indian Institute of Management, Ahmedabad for his new findings
