Question
Find the difference between sum of digits of LCM and
HCF of 28, 42 and 70.Solution
28 = 2² × 7 42 = 2 × 3 × 7 And 70 = 2 × 5 × 7 So, HCF = 2 × 7 = 14 So, sum of digits of HCF = 1 + 4 = 5 And LCM = 2² × 3 × 5 × 7 = 420 And sum of digits of LCM = 4 + 2 + 0 = 6 So, required difference = 6 - 5 = 1 Hence, option a.
