What are the factors of a number?

Factors of a number 'n' are the integers that can able to divide the original number 'n' into equal parts without any remainder. for example, let us consider the integer 8 and let us check the factors of 8. they are 1, 2, and 4, because they can divide the integer 8 without any remainder.

How to find factors of an integer using the R Program?

In this R program, we give the number directly to the function print_factors(). Inside the function, using for loop iterate through the values from 1 to a given integer. Check each number if that perfectly divides the given integer using the mod operator, if yes print that number. Finally, we get the list of factors.

ALGORITHM

STEP 1: Call function print_factors()

STEP 2: Pass the number whose factors need to be found as the function argument.

STEP 3: Using for loop iterate from 1 to the given integer

STEP 4:check if the iterated value perfectly divides our integer

STEP 5:if gives the remainder zero print the value

STEP 6:continue the loop until iteration reaches our number

R Source Code

                                          print_factors <- function(k) {
print(paste("The factors of given number",k,"are:"))
for(i in 1:k) {
if((k %% i) == 0) {
print(i)
}
}
}
print_factors(120)
                                      

OUTPUT

[1] "The factors of given number 120 are:"
[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 8
[1] 10
[1] 12
[1] 15
[1] 20
[1] 24
[1] 30
