Project Euler & HackerRank Problem 20 Solution. Factorial digit sum. by { BetaProjects} | MAY 18, 2009 | Project Euler & HackerRank. Project Euler Problem 20

Factorial of 20 means that you multiply 20 by every number below it. Therefore, you calculate the factorial of 20 by multiplying 20 by 19 and then by 18 and so on all the way down to 1. In other words, we calculate 20 × 19 × 18 × × 1 to get 20 factorial. The answer to 20 factorial (20!) contains 19 digits, and below is the exact entire answer

= 20*19*18*17*16*15*14*13*12*11*10*9*8*7*6*5*4*3*2*1. 20*19*18*17*16*15 = 27907200. 14*13*12*11*10 = 240240. 9*8*7*6 = 3024. 5*4*3*2*1=120. So 20! = 27907200*240240 * 3024 *120.
