Thanks Bob. But is the multiplier 2 for 36 unique? I cannot find any other number.
Look at number 36. If you multiply the two individual digits and then the product by 2 you get 36.
So 36 = (3x6)x2
Is there any other number that can duplicate this? Namely ABCD--n digits = (AxBxCxDx--n digits) x2? If not why not? I found other numbers with different multipliers like:
144 = (1x4x4)x9 and 224 = (2x2x4)x14
Are these unique numbers?
