Find The Missing Numbers
Thanks Regina B
The last 2 digits of the answer are found by adding the numbers together.
12,  9*9*3=9321,  and 8*12*4=6424.
The digit in front of that is found by counting the number of digits, not numbers.
Example: 4*6*2 has 3 digits (6312) and 9*9*3 has 3 digits (9321) and 8*12*4 has 4 digits (6424).
The number out front is then found by finding the least common multiple, not including 1 and add them together for each one.
So 4*6*2 and 8*12*4 all have 2 as the least common multiple, (2+2+2=6 for both) so...4*6*2=6312, and 8*12*4=6424 and 3 is the least common multiple for 9*9*3 so 3+3+3=9 so...(9*9*3=9321).
Then you're done. Repeat that pattern for 20*15*5
