Question

Greatest number which divide 89,57,77 leaving 5 as remainder in each case

Answer 1

subtract 5 from each number
89-5= 84
57-5=52
77-5=72
then find the h.cf of 84, 52, 72
first find hcf of 84 & 52
84= 52×1+32 ( by euclid method)
52=32×1+20
32=20×1+12
20=12×1+8
12=8×1+4
8=4×2+0
then find the hcf of 4 & 72
72=4×18+0
hence the greatest no. is 72
