Python Prime Factors Program – This Python program will take a number as input from the user. It will display prime factors of that number.
We will study prime factors before writing the Python program to find them.
Definition of Prime Factor
A factor that is a prime number is called a Prime Factor.
We can say that prime factors are any set of prime numbers that will give the original number when multiplied.
Example: Find prime factors of 15
The prime factors of 15 are 3 and 5.
Note that 3 and 5 are prime numbers.
Question: Find prime factors of 15
The prime factors of 12 are 2, 2 and 3.
Note that 2, 2 and 3 are prime numbers.
Another Example: Find prime factors of 15
The prime factors of 35 are 5 and 7.
Note that 5 and 7 are prime numbers.
