420

Step-by-step:

the only numbers that we can use are 12, 1, 4 and 7

we can use brackets,-,+,×, as often as we want

12 and 7 are the largest numbers there so we can times them... that leaves 4 and 1 therefore we can add them and times the result by (12×7)

so...

(12×7)×(4+1)

12×7= 84

and...

4+1=5

84×5= 420

thus...the largest number he can make is 420
