1! = 1 2! = 2 x 1 = 2 3! = 3 x 2 x 1 = 6 4! = 4 x 3 x 2 x 1 = 24 5! = 5 x 4 x 3 x 2 x 1 = 120 6! = 6 x 5 x 4 x 3 x 2 x 1 = 720 7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5040 8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40320 9! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 362880 10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 3628800
将它们相加： 1 + 2 + 6 + 24 + 120 + 720 + 5040 + 40320 + 362880 + 3628800 = 4037913
所以，1到10的阶乘的和是4037913。
