## I have my exam tomorrow plz solve fast Q33. Use Euclid's Algorithm to find the HCF of 595 and 252 and express it in the form 595 m + 252n.                                              [ Ans. HCF (595, 252) = 7 and 7 = 595 (–11) + 252 (26) Here m = – 11, n = 26] Q34. If d = HCF of a and b, then d = na + mb, where m and n are integers, i.e., HCF of a and b is linear combination of a and b. Verify the above result for a =384, b = 26, i.e., verify that HCF of 384 and 26 is a linear combination of 384 and 26.                                                                                                                            [HOTS ] (CBSE 2007 )
