You can use a JavaScript lib called BigInteger.js for the purpose.it is an arbitrary-length integer library for Javascript, allows arithmetic operations on integers of unlimited size, notwithstanding memory and time limitations.This lib can be download from this link.Like var largeNumber = bigInt("75643564363473453456342378564387956906736546456235345"); You can find documentation of lib here https://www.npmjs.com/package/big-integer
