APP description

A positive integer factorial means multiplying from 1 by 2 by 3 by 4 until the required number is multiplied.

For example, if the required number is 4, the factorial is 1 × 2 × 3 × 4, and the obtained product is 24, and 24 is the factorial of 4. For example, if the required number is 6, the factorial is 1 × 2 × 3 × ... × 6, and the obtained product is 720, and 720 is the factorial of 6. For example, if the required number is n, the factorial is 1 × 2 × 3 × ... × n, and the obtained product is x, and x is the factorial of n.

Any natural number n factorial representation greater than 1:

n!=1×2×3×......×n or n!=n×(n-1)! \(n!=1\times 2\times 3\cdot\times n=n\times(n-1)!=\prod_{i=1}^{n}i\)
