# Intuition
<!-- The Simple way to do this. -->

# Approach
<!-- Straight forward and simple -->

# Complexity
- Time complexity:
<!-- Add your time complexity here, e.g. $$O(n)$$ -->

- Space complexity:
<!-- Add your space complexity here, e.g. $$O(n)$$ -->

# Code
```dart []
class Solution {
  int numberOfPairs(List<int> nums1, List<int> nums2, int k) {
    int count=0;
    for(int i=0;i<nums1.length;i++){
        for(int j=0;j<nums2.length;j++){
            if(nums1[i] % (nums2[j]*k)==0){
                count++;
            }
        }
    }
    return count;
  }
