Step 8: 2191 + 313 = 2504
Step 9: 2504 + 313 = 2817
Step 10: 2817 + 313 = 3130
Step 11: 3130 + 313 = 3443
Step 12: 3443 + 313 = 3756
Step 13: 3756 + 313 = 4069
Step 14: 4069 + 313 = 4382
Step 15: 4382 + 313 = 4695
Step 16: 4695 + 313 = 5008
Step 17: 5008 + 313 = 5321
Step 18: 5321 + 313 = 5634
Step 19: 5634 + 313 = 5947
Step 20: 5947 + 313 = 6260
Step 21: 6260 + 313 = 6573
Step 22: 6573 + 313 = 6886
Step 23: 6886 + 313 = 7199
Step 24: 7199 + 313 = 7512
Step 25: 7512 + 313 = 7825
Step 26: 7825 + 313 = 8138
Step 27: 8138 + 313 = 8451
Step 28: 8451 + 313 = 8764
Step 29: 8764 + 313 = 9077
Step 30: 9077 + 313 = 9390
Step 31: 9390 + 313 = 9703
Step 32: 9703 + 313 = 10016
Step 33: 10016 + 313 = 10329
Step 34: 10329 + 313 = 10642
Step 35: 10642 + 313 = 10955
Step 36: 10955 + 313 = 11268
Step 37: 11268 + 313 = 11581
Step 38: 11581 + 313 = 11894
Step 39: 11894 + 313 = 12207
Step 40: 12207 + 313 = 12520
Step 41: 12520 + 313 = 12833
Step 42: 12833 + 313 = 13146
Step 43: 13146 + 313 = 13459
Step 44: 13459 + 313 = 13772
Step 45: 13772 + 313 = 14085

So, 313*45 = 14085
