Step 346: 19320 + 56 = 19376
Step 347: 19376 + 56 = 19432
Step 348: 19432 + 56 = 19488
Step 349: 19488 + 56 = 19544
Step 350: 19544 + 56 = 19600
Step 351: 19600 + 56 = 19656
Step 352: 19656 + 56 = 19712
Step 353: 19712 + 56 = 19768
Step 354: 19768 + 56 = 19824
Step 355: 19824 + 56 = 19880
Step 356: 19880 + 56 = 19936
Step 357: 19936 + 56 = 19992

So, 56*357 = 19992
