Step 308: 167315 + 545 = 167860
Step 309: 167860 + 545 = 168405
Step 310: 168405 + 545 = 168950
Step 311: 168950 + 545 = 169495
Step 312: 169495 + 545 = 170040
Step 313: 170040 + 545 = 170585
Step 314: 170585 + 545 = 171130
Step 315: 171130 + 545 = 171675
Step 316: 171675 + 545 = 172220
Step 317: 172220 + 545 = 172765

So, 545*317 = 172765
