Step 2: Then apply the Euclid's division algorithm to 225 and 135 to obtain
225=135×1+90
Repeat the above step until you will get remainder as zero.
Step 3: Now consider the divisor 135 and the remainder 90, and apply the division lemma to get
135=90×1+45
90=2×45+0
Since the remainder is zero, we cannot proceed further.
Step 4: Hence, the divisor at the last process is 45
So, the H.C.F. of 135 and 225 is 45.
(ii) 196 and 38220
Step 1: First find which integer is larger.
38220>196
Step 2: Then apply the Euclid's division algorithm to 38220 and 196 to obtain
38220=196×195+0
Since the remainder is zero, we cannot proceed further.
Step 3: Hence, the divisor at the last process is 196.
So, the H.C.F. of 196 and 38220 is 196.
(iii) 867 and 225
Step 1: First find which integer is larger.
867>255
Step 2: Then apply the Euclid's division algorithm to 867 and 255 to obtain
867=255×3+102
Repeat the above step until you will get remainder as zero.
Step 3: Now consider the divisor 225 and the remainder 102, and apply the division lemma to get
255=102×2+51
102=51×2=0
Since the remainder is zero, we cannot proceed further.
Step 4: Hence the divisor at the last process is 51.
So, the H.C.F. of 867 and 255 is 51.
