Exercise 1.1(NCERT Book)
Question – 1: Use Euclid’s division algorithm to find the HCF of: (i) 135 and 225 (ii) 196 and 38220 (iii) 867 and 255 (i) By Euclid’s Division Algorithm, we have225 = 135 x 1 + 90 135= 90 x 1 + 45 90= 45 x 2 + 0∴ HCF (135, 225) = 45 (ii)ByContinue reading “Exercise 1.1(NCERT Book)”
Real Numbers
Euclid Division Alogrith Euclid’s division algorithm is a way to find the HCF of two numbers by using Euclid’s division lemma. It states that if there are any two integers a and b, there exists q and r such that it satisfies the given condition a = bq + r where 0 ≤ r < b.Continue reading “Real Numbers”
