Explanation:
We need to list
all the factors of each given number. A factor is a whole number that divides the given number evenly (with no remainder). To find all factors, we can test numbers from 1 up to the square root of the number, and for each divisor we find, we also include its pair.
Let’s go one by one:
1)
62
Check divisors:
- 1 × 62 = 62 → factors: 1, 62
- 2 × 31 = 62 → factors: 2, 31
- 3? 62 ÷ 3 = 20.666… no
- 4–30? none divide evenly
So factors:
1, 2, 31, 62
2)
44
- 1 × 44 → 1, 44
- 2 × 22 → 2, 22
- 4 × 11 → 4, 11
- 5? 44 ÷ 5 = 8.8 → no
- 6,7,8,9,10? no
So factors:
1, 2, 4, 11, 22, 44
3)
74
- 1 × 74 → 1, 74
- 2 × 37 → 2, 37
- 3? 74 ÷ 3 ≈ 24.66 → no
- 4–36? none
So factors:
1, 2, 37, 74
4)
25
- 1 × 25 → 1, 25
- 5 × 5 → 5 (only once)
So factors:
1, 5, 25
5)
57
- 1 × 57 → 1, 57
- 3 × 19 = 57 → 3, 19
- 2? 57 ÷ 2 = 28.5 → no
- 4–18? none
So factors:
1, 3, 19, 57
6)
75
- 1 × 75 → 1, 75
- 3 × 25 → 3, 25
- 5 × 15 → 5, 15
- 75 ÷ 7 ≈ 10.7 → no
So factors:
1, 3, 5, 15, 25, 75
7)
10
- 1 × 10 → 1, 10
- 2 × 5 → 2, 5
So factors:
1, 2, 5, 10
8)
24
- 1 × 24 → 1, 24
- 2 × 12 → 2, 12
- 3 × 8 → 3, 8
- 4 × 6 → 4, 6
So factors:
1, 2, 3, 4, 6, 8, 12, 24
9)
39
- 1 × 39 → 1, 39
- 3 × 13 → 3, 13
So factors:
1, 3, 13, 39
10)
68
- 1 × 68 → 1, 68
- 2 × 34 → 2, 34
- 4 × 17 → 4, 17
So factors:
1, 2, 4, 17, 34, 68
11)
42
- 1 × 42 → 1, 42
- 2 × 21 → 2, 21
- 3 × 14 → 3, 14
- 6 × 7 → 6, 7
So factors:
1, 2, 3, 6, 7, 14, 21, 42
12)
48
- 1 × 48 → 1, 48
- 2 × 24 → 2, 24
- 3 × 16 → 3, 16
- 4 × 12 → 4, 12
- 6 × 8 → 6, 8
So factors:
1, 2, 3, 4, 6, 8, 12, 16, 24, 48
13)
14
- 1 × 14 → 1, 14
- 2 × 7 → 2, 7
So factors:
1, 2, 7, 14
14)
27
- 1 × 27 → 1, 27
- 3 × 9 → 3, 9
So factors:
1, 3, 9, 27
15)
77
- 1 × 77 → 1, 77
- 7 × 11 → 7, 11
So factors:
1, 7, 11, 77
Now double-check each for completeness and correctness — all look good.
