Given two integer p and q, the task is to find the minimum possible number x such that q % x = 0 and x % p = 0. If the conditions aren’t true for any number then print -1.
Input: p = 3, q = 99
99 % 3 = 0
3 % 3 = 0
Input: p = 2, q = 7
Approach: If a number x satisfies the given condition then it’s obvious that q will be divided by p i.e. q % p = 0 because x is a multiple of p and q is a multiple of x.
So the minimum possible value of x will be the GCD of p and q and when q is not divisible by p then no number will satisfy the given condition.
Below is the implementation of the above approach:
- Minimum and Maximum element of an array which is divisible by a given number k
- Minimum number of given moves required to make N divisible by 25
- Minimum removals in a number to be divisible by 10 power raised to K
- Highest power of a number that divides other number
- Highest power of two that divides a given number
- Largest number that divides x and is co-prime with y
- Check if the sum of digits of a number N divides it
- Check if a given number divides the sum of the factorials of its digits
- Find a number that divides maximum array elements
- Highest power of 2 that divides a number represented in binary
- Greatest divisor which divides all natural number in range [L, R]
- Find maximum power of a number that divides a factorial
- Find integers that divides maximum number of elements of the array
- Count the number of pairs (i, j) such that either arr[i] is divisible by arr[j] or arr[j] is divisible by arr[i]
- Minimum positive integer divisible by C and is not in range [A, B]
