Question 21 (B) The H.C.F of 85 and 238 is expressible in the form 85m − 238. Find the value of m.To find HCF of 85 and 238, We do prime factorization of both 85 = 5 × 17 238 = 2 × 7 × 17 ∴ HCF = 17 Writing HCF in terms of 85m − 238 HCF = 85m − 238 17 = 85m − 238 17 + 238 = 85m 255 = 85m 85m = 255 m = 255/85 m = 3
