Javascript - code check for multiple of 3 and 5

To check if a number is a multiple of both 3 and 5, you can use the modulo operator %. If the remainder when dividing the number by 3 is 0 and the remainder when dividing the number by 5 is also 0, then the number is a multiple of both 3 and 5.

Here's a JavaScript function to check if a number is a multiple of both 3 and 5:

function isMultipleOf3And5(number) { return number % 3 === 0 && number % 5 === 0; } // Example usage console.log(isMultipleOf3And5(15)); // true, since 15 is a multiple of both 3 and 5 console.log(isMultipleOf3And5(9)); // false, since 9 is a multiple of 3 but not of 5 console.log(isMultipleOf3And5(10)); // false, since 10 is a multiple of 5 but not of 3

In this function:

  • number % 3 === 0 checks if number is divisible by 3 without any remainder.
  • number % 5 === 0 checks if number is divisible by 5 without any remainder.
  • If both conditions are true, then the function returns true, indicating that the number is a multiple of both 3 and 5. Otherwise, it returns false.

  4. "JavaScript code to find multiples of 3 and 5 up to a certain limit" Description: This query seeks JavaScript code to find multiples of both 3 and 5 within a specified range or up to a certain limit. It's useful for generating sequences or analyzing numerical data.

    function findMultiplesOf3And5InRange(start, end) { const multiples = []; for (let i = start; i <= end; i++) { if (i % 3 === 0 && i % 5 === 0) { multiples.push(i); } } return multiples; } // Example usage: const start = 1; const end = 30; const multiples = findMultiplesOf3And5InRange(start, end); console.log("Multiples of both 3 and 5:", multiples);

  5. "JavaScript function to determine if a number is divisible by both 3 and 5" Description: This query is about finding a JavaScript function to determine if a given number is divisible by both 3 and 5. It's often needed in mathematical calculations or conditional logic.

    function isDivisibleBy3And5(number) { return number % 3 === 0 && number % 5 === 0; } // Example usage: const num = 45; if (isDivisibleBy3And5(num)) { console.log(`${num} is divisible by both 3 and 5.`); } else { console.log(`${num} is not divisible by both 3 and 5.`); }

  6. "JavaScript check if a number is a multiple of both 3 and 5" Description: This query seeks JavaScript code to check if a given number is a multiple of both 3 and 5. It's a basic arithmetic operation commonly used in mathematical algorithms.

    function isMultipleOf3And5(number) { return number % 3 === 0 && number % 5 === 0; } // Example usage: const num = 20; if (isMultipleOf3And5(num)) { console.log(`${num} is a multiple of both 3 and 5.`); } else { console.log(`${num} is not a multiple of both 3 and 5.`); }

  7. "JavaScript code to identify numbers divisible by 3 and 5 in an array" Description: This query looks for JavaScript code to identify numbers within an array that are divisible by both 3 and 5. It's useful for data analysis or filtering operations on arrays of numerical values.

    function findDivisibleBy3And5(numbers) { return numbers.filter(num => num % 3 === 0 && num % 5 === 0); } // Example usage: const numbers = [15, 6, 10, 30, 9]; const divisibleNumbers = findDivisibleBy3And5(numbers); console.log("Numbers divisible by both 3 and 5:", divisibleNumbers);

  8. "JavaScript code to check if number is a multiple of 3 and 5 using if condition" Description: This query seeks JavaScript code using an if condition to check if a given number is a multiple of both 3 and 5. It's a fundamental programming concept often used in control flow logic.

    function isMultipleOf3And5(number) { if (number % 3 === 0 && number % 5 === 0) { return true; } else { return false; } } // Example usage: const num = 25; if (isMultipleOf3And5(num)) { console.log(`${num} is a multiple of both 3 and 5.`); } else { console.log(`${num} is not a multiple of both 3 and 5.`); }

  9. "JavaScript function to determine if a number is a multiple of 3 and 5 using modulus" Description: This query is about finding a JavaScript function to determine if a given number is a multiple of both 3 and 5 using the modulus operator.
