• 928 ÷ 14 = 66.286 — not a whole number
• 928 ÷ 15 = 61.867 — not a whole number
• 928 ÷ 16 = 58 — so 16 and 58 are factors
• 928 ÷ 17 = 54.588 — not a whole number
• 928 ÷ 18 = 51.556 — not a whole number
• 928 ÷ 19 = 48.842 — not a whole number
• 928 ÷ 20 = 46.4 — not a whole number
• 928 ÷ 21 = 44.19 — not a whole number
• 928 ÷ 22 = 42.182 — not a whole number
• 928 ÷ 23 = 40.348 — not a whole number
• 928 ÷ 24 = 38.667 — not a whole number
• 928 ÷ 25 = 37.12 — not a whole number
• 928 ÷ 26 = 35.692 — not a whole number
• 928 ÷ 27 = 34.37 — not a whole number
• 928 ÷ 28 = 33.143 — not a whole number
• 928 ÷ 29 = 32 — so 29 and 32 are factors
• 928 ÷ 30 = 30.933 — not a whole number
