Use euclid,s division algorithim to find the HCF of 135 and 225 |
|
Answer» 225=135×1+90135=90×1+45 90=45×2+0This implies that HCF is 45 Since 225>135 , We divided 225 by135 225÷135=90 .Since remainder is not 0 ,We divided 135 by 90 135÷90=45 .Since remainder is not 0,We divided 90 by 4590÷45=0, Since the remainder is 0 .So as using the euclids division algorithim the H.C.F is 45 |
