$\huge\blue{\overbrace{\blue{\underbrace{\color{blue}{{ \blue\:{Answer}}}}}}}$

The HCF of 252 and 198 is 18

Step-by-step explanation:

Given two numbers 252 and 198

we have to find the HCF using Euclid division algorithm

Euclid division algorithm states that for any two positive inters a and b there exist a unique integers q and r such that

a=bq+r where

HCF= 18
