When numbers are close together, the HCF will also be a factor of the sum and of the difference of the numbers.
So 411 and 417. The sum is 828 and the diffence is 6. 2 is not a common factor but 3 is
411 / 3 = 147 417/3 = 139. This is useful if the numbers are close together.
This is the Sutra By addition and by subtration.
Try this one for yourself:-
