You first look at the number that is before the !(factorial sign). Then you times all positive integers (which means it doesn't include 0), including the number itself. The answer is the factorial of the original number beside the ! sign. EX.:4!=1x2x3x4=24
The value of 9 factorial plus 6 factorial is 363,600
27 factorial = 10,888,869,450,418,352,160,768,000,000
1 factorial = 1
Zero factorial = 1
Factorial 65 = 8247650592082470666723170306785496252186258551345437492922123134388955774976000000000000000
The value of 9 factorial plus 6 factorial is 363,600
It is 4060.
factorial of -1
Factorial 6 = 720
27 factorial = 10,888,869,450,418,352,160,768,000,000
1 factorial = 1
Zero factorial = 1
Factorial 65 = 8247650592082470666723170306785496252186258551345437492922123134388955774976000000000000000
18 factorial is 6,402,373,705,728,000.
34 factorial = 295,232,799,039,604,140,847,618,609,643,520,000,000.
26 factorial is 403,291,461,126,605,635,584,000,000
As we know product of no numbers at all is 1 and for this reason factorial of zero =1and we know factorial of 1=1
