# Python Program to find the factors of a number
# This function computes the factor of the argument passed
def print_factors[x]:
print["The factors of",x,"are:"]
for i in range[1, x + 1]:
if x % i == 0:
print[i]
num = 320
print_factors[num]
Output
The factors of 320 are: 1 2 4 5 8 10 16 20 32 40 64 80 160 320
Note: To find the factors of another number, change the value of num
.
In this program, the number whose factor is to be found is stored in num
, which is passed to the print_factors[]
function. This value is assigned to the variable x in print_factors[]
.
In the function, we use the for
loop to iterate from i equal to x. If x is perfectly divisible by
i, it's a factor of x.

Here is an example if you want to use the primes number to go a lot faster. These lists are easy to find on the internet. I added comments in the code.
