Answer: The approximate value of 100! is 9.3326215443944E+157

The value of 100 factorial (100!) is a large number that can be calculated using mathematical software or calculators designed to handle such computations. Calculating it manually is highly impractical due to the number of multiplications involved.

However, you can express the result approximately using scientific notation:

100! ≈ 9.33 x 10¹⁵⁷

This means that 100 factorial is approximately 9.33 followed by 157 zeros. It’s an extremely large number and demonstrates the rapid growth of factorials as the input increases. Calculators and computer software are the most efficient tools for calculating such large factorials.
