# R Program to check the square root of a number is prime or not

In this program, You will learn how to check the square root of a number is prime or not in R.

`Some list of Prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19`

## Example: How to check the square root of a number is prime or not in R

```
{
num = as.integer(readline(prompt = "Enter a number :"))
n = sqrt(num)
print(paste("Square root is :", n))
#Convert to integer now for remove decimal value
n = as.integer(n)
f = 1
i = 2
while (i <= n / 2) {
if (n %% i == 0) {
f = 0
break
}
i = i + 1
}
if (f == 1) {
print(paste("Number is prime :", n))
} else{
print(paste("Number is not prime :", n))
}
}
```

#### Output:

```
Enter a number :49
[1] "Square root is : 7"
[1] "Number is prime : 7"
```
