Smallest Number which divides 2, 4, 6 and leaves remainder 0
= LCM of 2, 4, 6
= 12
We need to find the greatest 3-digit number which will divide 2, 4, 6
Greatest 3 digit number = 999
We divide 999 by 12
So remainder is 3
But we need to find a number where remainder is 0.
So, 996 is the greatest 3 digit number
