777777 is divisible by 11. It is also divisible by: 3. 3 X 259259 = 777777. 7. 7 X 111111 = 777777. 11. 11 X 70707 = 777777. 13. 13 X 59829 = 777777. 77. 77 X 10101 = 777777. 259. 259 X 3003 = 777777. 777. 777 X 1001 = 777777. And of course, 777777 is divisible by all the factors following the X's above. There are probably others, but 881.9 is the square root. So we don't have to look for any greater than that, if we do a systematic search through the primes. The question does not specify prime factors. What a fun number. Who knew?
