DESCRIPTION:

Create a function that checks if a number n is divisible by two numbers x AND y. All inputs are positive, non-zero numbers.

Examples:
1) n =   3, x = 1, y = 3 =>  true because   3 is divisible by 1 and 3
2) n =  12, x = 2, y = 6 =>  true because  12 is divisible by 2 and 6
3) n = 100, x = 5, y = 3 => false because 100 is not divisible by 3
4) n =  12, x = 7, y = 5 => false because  12 is neither divisible by 7 nor 5

 

설명:

숫자 n이 x 그리고 y 두 숫자로 나누어지는지 확인하는 함수를 작성하세요. 모든 입력은 0이 아닌 양수입니다.

Examples:
1) n =   3, x = 1, y = 3 =>  true because   3 is divisible by 1 and 3
2) n =  12, x = 2, y = 6 =>  true because  12 is divisible by 2 and 6
3) n = 100, x = 5, y = 3 => false because 100 is not divisible by 3
4) n =  12, x = 7, y = 5 => false because  12 is neither divisible by 7 nor 5

 

풀이

n을 x로 나눈 나머지가 0이고 n을 y로 나눈 나머지가 모두 참이면 true를 그렇지 않다면 false를 반환했다. 

 

코드

function isDivisible(n, x, y) {
  return n % x === 0 && n % y === 0;
}
