Itroductio umber theory, called the Quee of Mathematics, is a broad ad diverse part of mathematics that developed from the study of the itegers. The foudatios for umber theory as a disciplie were laid by the Greek mathematicia Pythagoras ad his disciples (kow as Pythagoreas).

A.VIJAYASAKAR, M. A. GOPALA ad V. KRITHIKA itself, is the Diophatie equatios sice its origis ca be foud i texts of the aciet Babyloias, Chiese, Egyptias, Greeks ad so o [7-8]. Diophatie problems were first itroduced by Diophatus of Alexadria who studied this topic i the third cetury AD ad he was oe of the first mathematicias to itroduce symbolism to Algebra. The theory of Diophatie equatios is a treasure house i which the search for may hidde relatio ad properties amog umbers form a treasure hut. I fact, Diophatie problems domiated most of the celebrated usolved mathematical problems. Certai Diophatie problems come from physical problems or from immediate mathematical geeralizatios ad others come from geometry i a variety of ways. Certai Diophatie problems are either trivial or difficult to aalyze [-]. Also oe may [9-5]. I this commuicatio, we attempt for obtaiig three o-zero distict itegers ad such that (i) p, q, (ii) p, q, (iii) p, q. Sectio A Method of Aalysis Let ad be ay two o-zero distict itegers such that, we write where a ad b are o-zero distict itegers. ow, 0 a b, 0 b a, p ( 0 ) ( a b) p. ()

As Diophatie problems are rich i variety, oe may attempt to fid other choices of Diophatie problems.
