To calculate reminder on dividing the number by 27 and 37
Let me explain this rule by taking examples
consider number 64564276, we have to calculate the reminder on diving
this number by 27 and 37 respectively.
Make triplets as written below starting from units place
64 564 276
now sum of all triplets = 64
+ 564 +
276 = 904
divide it by 27 we get reminder as 13
divide it by 37 we get reminder as 16
Example.
Let the number is 2387850765
triplets are 2...387...850...765
sum of the triplets = 2+387+850+765 = 2004
on revising the steps we get
2 004
sum = 6
divide it by 27 we get reminder as 6
divide it by 37 we get reminder as 6
