N = number that must be inserted in the given numbers
to be divisible by 6
=> 3n
=> 85n
Now, let’s find a best number that will multiplied with both given number and
is divisible with 6.
=> 85n / 6
=> 85(6) / 6
=> 510 / 6
=>n = 6
now, let’s try to 3
=> 3(6) / 6
=> 18 / 6
=> 3
Thus, the value of N is 6 because it is divisible by 6 when multiplied to the
given number.
