997
17×59×997
Answer is 16
(What is the shortest way to solve this as I tried a complicated method.
I directly divided this by the largest 3 digit prime number i.e, 997 and got the result)
We can write 999991 as difference of two perfect squares ,
999991 = 1000000 – 9 = 1000² – 3² = (1000 – 3 ) ( 1000 + 3 )
997 is the answer
sum of T+G = 9+7= 16
