A divisibility checker is a tool or algorithm used to determine if one number is divisible by another without leaving a remainder. It typically involves performing a division operation and checking if the remainder is zero. For example, to check if a number ( a ) is divisible by another number ( b ), you would divide ( a ) by ( b ) and see if the remainder is zero. If it is zero, then ( a ) is divisible by ( b ), otherwise it is not. Divisibility checkers are often used in mathematics and computer programming for various applications such as determining factors, simplifying fractions, and solving mathematical problems.

function checkDivisibility() {
var num = document.getElementById("num").value;
var divisor = document.getElementById("divisor").value;
if (num % divisor === 0) {
document.getElementById("result").innerHTML = num + " is divisible by " + divisor;
} else {
document.getElementById("result").innerHTML = num + " is not divisible by " + divisor;
}
}
</script>

This HTML code creates a basic web page with input fields for the dividend and divisor, a "Check" button, and a paragraph element to display the result. The JavaScript function checkDivisibility() is called when the button is clicked, which calculates whether the dividend is divisible by the divisor and displays the result accordingly.
