- 613 ÷ 3 = 204.333 — not a whole number
- 613 ÷ 4 = 153.25 — not a whole number
- 613 ÷ 5 = 122.6 — not a whole number
- 613 ÷ 6 = 102.167 — not a whole number
- 613 ÷ 7 = 87.571 — not a whole number
- 613 ÷ 8 = 76.625 — not a whole number
- 613 ÷ 9 = 68.111 — not a whole number
- 613 ÷ 10 = 61.3 — not a whole number
- 613 ÷ 11 = 55.727 — not a whole number
- 613 ÷ 12 = 51.083 — not a whole number
- 613 ÷ 13 = 47.154 — not a whole number
- 613 ÷ 14 = 43.786 — not a whole number
- 613 ÷ 15 = 40.867 — not a whole number
- 613 ÷ 16 = 38.313 — not a whole number
- 613 ÷ 17 = 36.059 — not a whole number
- 613 ÷ 18 = 34.056 — not a whole number
- 613 ÷ 19 = 32.263 — not a whole number
- 613 ÷ 20 = 30.65 — not a whole number
- 613 ÷ 21 = 29.19 — not a whole number
- 613 ÷ 22 = 27.864 — not a whole number
- 613 ÷ 23 = 26.652 — not a whole number
- 613 ÷ 24 = 25.542 — not a whole number
Collecting both numbers from every successful division gives the complete list: 1 and 613.
