| 3) The sum of all the factors of 35 is the 2nd multiple of a number. SOLUTION 1 : Step 1: Factors of 35 → 1, 5, 7,and 35. Step 2: 1 + 5 + 7 + 35 = 48 Step 3: 2nd multiple = 48 Step 4: 48 ÷ 2 = 24 The number is 24. |
| 4) The sum of all the factors of 44 is the 6th multiple of a number. SOLUTION 1 : Step 1: Factors of 44 → 1, 2, 4, 11, 22 and 44. Step 2: 1 + 2 + 4 + 11 + 22 + 44 = 84 Step 3: 6th multiple = 84 Step 4: 84 ÷ 6 = 14 The number is 14. |
| 5) The sum of all the factors of 24 is the 4th multiple of a number. SOLUTION 1 : Step 1: Factors of 24 → 1, 2, 3, 4, 6, 8, 12 and 24. Step 2: 1 + 2 + 3 + 4 + 6 + 8 + 12 + 24 = 60 Step 3: 4th multiple = 60 Step 4: 60 ÷ 4 = 15 The number is 15. |
| 6) The sum of all the factors of 18 is the 3rd multiple of a number. SOLUTION 1 : Step 1: Factors of 18 → 1, 2, 3, 6, 9 and 18. Step 2: 1 + 2 + 3 + 6 + 9 + 18 = 39 Step 3: 3rd multiple = 39 Step 4: 39 ÷ 3 = 13 The number is 13. |
| 7) The sum of all the factors of 22 is the 2nd multiple of a number. SOLUTION 1 : Step 1: Factors of 22 → 1, 2, 11, and 22. Step 2: 1 + 2 + 11 +22 = 36 Step 3: 2nd multiple = 36 Step 4: 36 ÷ 2 = 18 The number is 18. |
| 8) The sum of all the factors of 35 is the 8th multiple of a number. SOLUTION 1 : Step 1: Factors of 35 → 1, 5, 7,and 35. Step 2: 1 + 5 + 7 + 35 = 48 Step 3: 8th multiple = 48 Step 4: 48 ÷ 8 = 6 The number is 6. |
| 9) The sum of all the factors of 27 is the 5th multiple of a number. SOLUTION 1 : Step 1: Factors of 27 → 1, 3, 9, and 27. Step 2: 1 + 3 + 9 + 27 = 40 Step 3: 5th multiple = 40 Step 4: 40 ÷ 5 = 8 The number is 8. |
| 10) The sum of all the factors of 22 is the 3rd multiple of a number. SOLUTION 1 : Step 1: Factors of 22 → 1, 2, 11, and 22. Step 2: 1 + 2 + 11 +22 = 36 Step 3: 3rd multiple = 36 Step 4: 36 ÷ 3 = 12 The number is 12. |
