A prime number is a positive integer that is only divisible by 1 and itself. For example, 2, 3, 5, 7, 11 are the first few prime numbers. Example: Check Prime Number // program to check if a number is prime or not // take input from the user const number = parseInt(prompt("...
JavaScript 算法之 判断是否为质数 prime number 素数 质数：只能被1和自己整除且大于1的数。合数：数大于1且因数多余2个（大于1的数质数的补集）。function isPrimeNumber1(n){if(n < 2) return false;if(n === 2) return true; // 最小的质数for(let i = 2; i < n; i++){if(n % i ...
// program to find the factors of an integer // take input const num = prompt('Enter a positive number: '); console.log(`The factors of ${num} is:`); // looping through 1 to num for(let i = 1; i <= num; i++) { // check if number is a factor if(num % i == 0)...
