# Algorithm and Flowchart to find Factorial of a number1 min read

This is the tutorial we will write an algorithm to find the factorial of a number, we will also learn to draw a flowchart to find Factorial of a number. You may go through the topic below to learn more about algorithms.

Let us start with a flowchart for factorial numbers.

## Flowchart to calculate the factorial of a number

The above flowchart diagram is to find the factorial number.

## Algorithm of factorial of a number

Step 1: Start
Step 2: Read a number n
Step 2: Initialize variables:
`i = 1`, `fact = 1 `
Step 3:  if `i <= n` go to step 4 otherwise go to step 7
Step 4: Calculate
`fact = fact * i`
Step 5: Increment the i by 1 (`i=i+1`) and go to step 3
Step 6: Print fact
Step 7: Stop
