In general, the factorial of a number N = N*(N-1)*(N-2)....1
Factorial of a non-negative integer n is the product of all positive integers less than or equal to n. Factorials are commonly encountered in permutations, combinations, number theory and series expansions of trigonometric and other functions (Taylor series).

Number of trailing zeros in 78! = 18
