You can find the multiples of a number in JavaScript by using a loop to iterate through a range of numbers and checking if each number is divisible by the target number javascript Step 3: Find the multiples of that number from the series using argwhere() function in the numpy library. The module operator performs division and gives you the remainder. If it is not a multiple, I need to find the closest multiple of the pattern length and change the result to that. Then instead of doing multiples = numbers[i]; you will like to push the right values inside the array, Alternatively you can also use array.reduce function. So, the multiples of 21 need to be discarded from the result. if (arr[i] % value = javascript Practice problems The first multiple of any number is the number itself. To check if a number is not a multiple of another number, we can use the modulo operator % but the remainder of first number by second number is not equal to 0.
