## How do you find the sum of the digits of a factorial?

Find sum of digits in factorial of a number

- Create a vector to store factorial digits and initialize it with 1.
- One by one multiply numbers from 1 to n to the vector. We use school mathematics for this purpose.
- Sum all the elements in vector and return the sum.

**What is the factorial of 100 answer?**

The aproximate value of 100! is 9.3326215443944E+157. The number of trailing zeros in 100! is 24. The number of digits in 100 factorial is 158.

### How many zeros are there in 100 factorial?

24

The number of zeros in 100! will be 24 .

### What is the total of 1 to 100?

The sum of all natural numbers from 1 to 100 is 5050. The total number of natural numbers in this range is 100. So, by applying this value in the formula: S = n/2[2a + (n − 1) × d], we get S=5050.

**What’s the highest factorial ever computed?**

### How many zeros will be there at the end of the expression 7 * 14 * 21 *?

Answer: Step-by-step explanation: 21 zeroes are there.

**How to find the sum of digits in a factorial?**

Since the factorial could be very large, we need to use an array (or hashmap) to store the digits of the answer. However, in some programming language, large values can be stored e.g. BigInteger in Java or Python. Similar to Digit factorials: Find the Sum of All the Curious Numbers, we will compute the factorial and store the value in a dictionary.

## Which is the correct result of 100 factorial?
