Indians are curious beings. And we have none other than Google's backing to make that statement. In its Year in Review 2021 listing for India, the tech giant revealed the top queries made by Indians on the internet this year. Among the top searches was a really tough math problem: What is the factorial of 100? Read on to know more.
The math problem was India's second most searched query on Google for this year. The topmost query was about Black fungus - an infection which circulated widely across India amid the country's deadly second wave of COVID-19. Other top queries were - "What is Taliban," "What is happening in Afghanistan," and "What is remdesivir," among others.
A factorial is the product of all the positive integers less than or equal to a given positive integer, according to Britannica website. It is denoted by the given positive integer followed by an exclamation mark. For example, if we are working to find the factorial of 4, it would be written as 4! And the answer would be: 1x2x3x4 or 24.
Similarly, the factorial of 100 can be calculated by multiplying all the numbers starting from one all the way to 100. The aproximate value of 100! is 9.3326215443944E+157. The number of trailing zeros in 100! is 24, and the number of digits is 158.
