## How do you find out if a number is a multiple of 3 JavaScript?

JavaScript Basic: Exercise-25 with Solution

Write a JavaScript program to check whether a given positive number is a multiple of 3 or a multiple of 7. ES6 Version: function test37(x) { if (x % 3 == 0 || x % 7 == 0) { return true; } else { return false; } } console. log(test37(12)); console.

## How do you check if a number is a multiple of another number?

Multiples of 2 can be written as the product of a counting number and 2 . The first six multiples of 2 are given below. A multiple of a number is **the product of the number and a counting number**. So a multiple of 3 would be the product of a counting number and 3 .

## How do you check if a number is a multiple of 5 in JavaScript?

**Use the modulus operator**: if (num % 5 == 0) //the number is a multiple of 5.

## How do you check if a number is divisible by another number in JavaScript?

We will use **the modulo operator, %** , to check if one number is evenly divisible by another number. The modulo operator gives the remainder obtained by dividing two numbers. If a number is evenly divisible, the operation will return 0 .

## How do you check if a number is divisible by 3 in JavaScript?

Method 3: Find using **sum of digits** :

One number is divisible by 3 if the sum of its digits is divisible by 3. For example, the sum of digits for 1236 is 1 + 2 + 3 + 6 = 12 = 1 + 2 = 3, which is divisible by 3.

## How do you check if a number is a multiple of 7?

**How to Tell if a Number is Divisible by 7**

- Take the last digit of the number you’re testing and double it.
- Subtract this number from the rest of the digits in the original number.
- If this new number is either 0 or if it’s a number that’s divisible by 7, then you know that the original number is also divisible by 7.

## How do you check if a number is a multiple of 6?

**Follow the steps to check if a large number is divisible by 6 or not.**

- Step 1: Check the unit place digit of the number. …
- Step 2: Check the sum of all digits of the number. …
- Step 3: If step 1 and step 2 say that the large number is divisible by 2 and 3 both then the large number is said to be divisible by 6.

## How do you check if a number is a multiple of 5?

To check whether a number is divisible by 5, we have **to see the last number is 0 or 5**. If that is 0 or 5, the number is divisible by 5, otherwise not.

## How do you check if a number is a multiple of 4?

Multiples of 4 are numbers in the 4 times table. A number is divisible by 4 if the last two digits are divisible by 4. **If you halve the tens and ones part of a number and the answer is even**, then it is a multiple of 4.

## How do you check if a number is a multiple of 4 Javascript?

Use **the % (modulus) operator** in Javascript and PHP, which returns the remainder when a is divided by b in a % b . The remainder will be zero when a is a multiple of b . Ex. You can use the modulus to find the remainder after a division and then if the remainder is equal to zero then it’s a multiple.

## What is a multiple of 5?

Multiples of 5 are: **5, 10, 15, 20, 25, 30, 35, 40, etc**. Each multiple is created by multiply 5 times some other number. Factors are the numbers used to create a multiple.

## How do you check if a number is a multiple of 3 and 5?

A number, x, is said to be a multiple of another number, y, if the remainder of x / y x/y x/y is 0. Similarly, a number, n, will be a multiple of 3 and 5 if the **remainder** of n / 3 n/3 n/3 and n / 5 n/5 n/5 is equal to 0.

## How do you know a number is divisible by 3?

A number is divisible by 3, **if the sum of its all digits is a multiple of 3 or divisibility by 3**. Sum of all the digits of 54 = 5 + 4 = 9, which is divisible by 3. Hence, 54 is divisible by 3.

## How many times a number can be divided by 2 JavaScript?

An integer n can be divided by 2: floor(log(n)/log(**2**)) times.

## How do you know if a number is evenly divisible?

To check if a number is evenly divisible by 7, **start by taking the last digit of the number you’re testing and doubling it**. Then subtract this number from the rest of the digits in the original number.
