Question

Find the greatest number that will divide 13782 422 leaving remainder 2 in each case

Answer 1

SUBSTRACT BY 2 BECAUSE LEAVE REMAINDER 2

==> 13782-2 = 13780

==> 422-2 = 420

FACTOR OF 13780 = 2*2*5*13*53

FACTOR OF 420 = 2*2*5*21

SO, 2*2*5 ==> 20

20 IS THE GREATEST NUMBER that will divide 13782 422 leaving remainder 2 in each case

I HOPE ITS HELPFUL
