Understanding Factors

What are factors? Factors are numbers that divide exactly into another number without leaving a remainder.

Example: Factors of 24

1 × 24 = 24
2 × 12 = 24
3 × 8 = 24
4 × 6 = 24

All factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

Key Concepts
  • Every number has at least two factors: 1 and itself
  • Prime numbers have exactly two factors (e.g., 7: factors are 1 and 7)
  • Composite numbers have more than two factors
  • Factor pairs multiply to give the original number

Problem-Solving Strategies

Step-by-Step Approach:
  1. Always start with 1 - It's always a factor!
  2. Check divisibility rules:
    • Even numbers are divisible by 2
    • Sum of digits divisible by 3? Then divisible by 3
    • Ends in 0 or 5? Divisible by 5
  3. Find factor pairs systematically
  4. Stop at the square root - Beyond that, you'll find mirrored pairs
Common Mistakes to Avoid
  • Forgetting that the number itself is always a factor
  • Missing factor pairs (like 4 and 6 for 24)
  • Confusing factors with multiples
  • Stopping too early when searching

Practice Guide & Examples

Step-by-step solution:

  1. Start with 1: 1 × 36 = 36 ✓
  2. Check 2: 2 × 18 = 36 ✓
  3. Check 3: 3 × 12 = 36 ✓
  4. Check 4: 4 × 9 = 36 ✓
  5. Check 5: 36 ÷ 5 = 7.2 ✗ (not a factor)
  6. Check 6: 6 × 6 = 36 ✓
  7. Stop! √36 = 6, we've reached the square root

All factors in order: 1, 2, 3, 4, 6, 9, 12, 18, 36

Is 17 a prime number?

  1. Check divisibility by 2: 17 is odd ✗
  2. Check divisibility by 3: 1+7=8, 8÷3=2.67 ✗
  3. Check 5: Doesn't end in 0 or 5 ✗
  4. Check 7: 17÷7=2.43 ✗
  5. Stop! √17 ≈ 4.12, so only need to check up to 4

Conclusion: 17 is prime - only factors are 1 and 17
