Question 7 Among the numbers below, which is the largest number that perfectly divides both 306 and 36? (a) 36 (b) 612 (c) 18 (d) 3 (e) 2 (f) 360The largest number that divides both 306 and 36 is the HCF of both numbers Also, note that HCF is also called GCD – Greatest Common Divisior Finding HCF of 306, 36 using Shortcut Method Thus, HCF of 306 & 36 = 3 × 3 × 2 = 18 Thus, answer is (c)
