Unlocking the Secrets of Factors: A JavaScript Journey
The Quest for Factors Begins
When it comes to understanding numbers, one crucial aspect is identifying their factors. But what exactly are factors? Simply put, a factor is a number that exactly divides another number without leaving a remainder. For instance, the factors of 12 are 1, 2, 3, 4, 6, and 12.
Cracking the Code: A JavaScript Solution
To find the factors of a positive number, we can harness the power of JavaScript. Our program prompts the user to enter a positive integer, and then we use a for loop to iterate from 1 to the entered number. The modulus operator % plays a vital role in checking if the number is exactly divisible by the current iteration i
.
const num = parseInt(prompt("Enter a positive integer: "));
for (let i = 1; i <= num; i++) {
//...
}
The Conditional Check
Within each iteration, we employ an if…else statement to verify if the condition num % i == 0
is met. If it is, we display the number, indicating that it’s a factor of the original number.
if (num % i === 0) {
console.log(`${i} is a factor of ${num}`);
}
Unraveling the Mystery
By combining these elements, we can create a program that efficiently finds the factors of a positive number. Take a look at the example below, which demonstrates this concept in action:
const num = parseInt(prompt("Enter a positive integer: "));
console.log(`The factors of ${num} are:`);
for (let i = 1; i <= num; i++) {
if (num % i === 0) {
console.log(`${i}`);
}
}
