203203 = 203000 + 203 = 203 (1000 + 1)

= 203 \times 1001 . Only factorizing, not

the largest prime . But now 203 and

1001 can be more easily factorized

with normal trial method . And after

that selecting the lorgest is easy one .

203 = 29 \times 7

1001 = 13 \times 11 \times 7

The largest is 29
