It is well known that Kloosterman sum and exponential sum are basic topics in number theory. By using Dwork's p-adic theory and method, particularly by using Dwork trace formula, we investigate the p-adic Newton polygon of L-function of dimension 3 twisted Kloosterman sum. We explore the asymptotic behavior of p-adic Newton polygon of L-function of twisted exponential sum of one-variable and two-variable polynomials of small degree. We study the p-adic Newton polygon of L-function of exponential sum of binomial x^d+ax^{d-1}. By using p-adic method, we study the periodicity of the arithmetic function associated with the least common multiple of consecutive quadratic progression terms and consecutive cubic progression terms and determine the smallest periods. By p-adic and analytic methods, we investigate the asymptotic behavior of the least common multiple of consecutive quadratic progression terms and consecutive cubic progression terms. This project will be important in science, and will make active and important contributions to number theory and algebraic geometry
