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
