Question
Find the greatest number that will divide 49, 147 and
322 to leave the same remainder in each case.Solution
According to the question, The differences will be, ⇒ 147 - 49 = 98 ⇒ 322 - 147 = 175 ⇒ 322 - 49 = 273 The set of numbers {98,175,273} Now HCF of {98,175,273} ⇒ 98 = 7 × 7 × 2 ⇒ 175 = 5 × 5 × 7 ⇒ 273 = 13 × 7 × 3 The HCF of {98,175,273} is 7
