Chapter : Real Numbers
Exercise : 1.1
Question 1. Use Euclid's division algorithm to find HCF of
(i) 135 and 225
(ii) 196 and 38220
(iii) 867 and 255
Solution 1.
(i) 135 and 225
Since 225>135, we can apply Euclid's division lemma to 225 and 135
225 = 135×1 + 90
Since the remainder 90≠0 , we can apply Euclid's division lemma to 135 and 90
135 = 90×1 + 45
Again we can see that the remainder 45≠0 we will again apply Euclid's division lemma to 90 and 45
90 = 45×2 + 0
We get remainder = 0
So in last step divisor is 45 so the HCF of 135 and 225 is 45.
