## JavaScript Math: Exercise-71 with Solution

Write a JavaScript program to print all the prime factors of a given number.

**Visualisation:**

**Test Data:**

(75) -> [3, 5, 5]

(18) -> [2, 3, 3]

(101) -> [101]

**Sample Solution:**

**HTML Code:**

```
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>JavaScript function to all prime factors of a given number</title>
</head>
<body>
</body>
</html>
```

**JavaScript Code:**

```
const Prime_Factors = (number) => {
const result_factors = []
for (let i = 2; i * i <= number; i++) {
while (number % i === 0) {
result_factors.push(i)
number = Math.floor(number / i)
}
}
if (number > 1) {
result_factors.push(number)
}
return result_factors
}
console.log(Prime_Factors(75))
console.log(Prime_Factors(18))
console.log(Prime_Factors(101))
```

Sample Output:

[3,5,5] [2,3,3] [101]
