To calculate 4! (read as “4 factorial”), you multiply all positive integers from 1 to 4. The formula for a factorial is:
n! =n×(n−1) ×(n−2) ×…×1
Step-by-step calculation:
- 4×3=12
- 12×2=24
- 24×1=24
Thus:
The value of 4! is 24. Factorials are commonly used in mathematics, especially in permutations, combinations, and probability calculations.
