Question

if r= 0, then what is the relation between a,b andq in a= bq+ r of Euclid divison lemma

Answer 1

$a = bq + r \\ a = bq$
This means that a is a multiple of b as well as q as both b and q divide a. Moreover, if b is co prime to q, then a is the LCM of b and q.
On the other hand , b and q are the divisors of a.
