The Least Common Multiple (LCM) of some numbers is the smallest number that the numbers are factors of. Like the LCM of 3 and 4 is 12, because 12 is the smallest number that 3 and 4 are both factors for. Type some numbers into the box to the right, and this page will find the LCM of those numbers. Type the integers here.
Squaring, you get 100m2+20mi+i2, and since both 100m2 and 20mi are multiples of 10, the units digit of the square is just the units digit of i2. Now just check 02, 12 etc. in turn and you'll find exactly which digits are possible units digit in a square.
