Question

Match the factorial to its value.

1. 7! 40,320
2. 5! 720
3. 8! 120
4. 6! 5,040

Answer 1

Even if you knew nothing about factorial, you can probably solve this by assuming the higher the factorial, the larger the answer.

A number factorial (x!) means "multiply that number by all the numbers below it, all the way to 1." So 7! = 7*6*5*4*3*2*1

Answer 2

\(5!\) is the smallest, then \(6!\) etc
