Step 312: 149280 + 480 = 149760
Step 313: 149760 + 480 = 150240
Step 314: 150240 + 480 = 150720
Step 315: 150720 + 480 = 151200
Step 316: 151200 + 480 = 151680
Step 317: 151680 + 480 = 152160
Step 318: 152160 + 480 = 152640
Step 319: 152640 + 480 = 153120
Step 320: 153120 + 480 = 153600
Step 321: 153600 + 480 = 154080
Step 322: 154080 + 480 = 154560
Step 323: 154560 + 480 = 155040
Step 324: 155040 + 480 = 155520
Step 325: 155520 + 480 = 156000
Step 326: 156000 + 480 = 156480
Step 327: 156480 + 480 = 156960
Step 328: 156960 + 480 = 157440
Step 329: 157440 + 480 = 157920

So, 480*329 = 157920
