Answer:
1.- 5,040
2.- 120
3.- 40,320
4.- 720
Explanation:
the factorial of a number is multiplying it by all the integers before it until 1.
Thus, we find the factorial of 7: 7!
1.- 7! = 7*6*5*4*3*2*1 = 5,040
and in this same way we find the other factorials:
2.- 5! =5*4*3*2*1 = 120
3.- 8!=8*7*6*5*4*3*2*1 = 40,320
4.- 6! = 6*5*4*3*2*1 =720
