Question

find the greatest number wch divides 17, 28 and 34 leaving remainders 2, 3,and 4 respectively

Answer 1

we have,
as it divides 17,28 and 34 leaving remainders 2,3,4 respectively
thus, 17-2=15, 28-3=25, and 34-4=30 are completely divisible by the req. no.
thus , the greatest number required for this condition is HCF(15,25,30)

since hcf of 15,25 and 30 is 5
Hence, the req. no. is 5
