Prime Factor: A factor that is also a prime number (has exactly 2 factors).

24 = 4 × 6
4 = 2 × 2
6 = 2 × 3
Step 1: Start with 24

Find two factors: 24 = 4 × 6

Applied rules:

• Systematic approach: Break down composite numbers step by step

• Prime identification: Stop when all factors are prime

• Verification: Multiply all prime factors to confirm

6 Real-world Application
Question 6
Eggs come in cartons of 12. If you need at least 50 eggs, what is the smallest number of cartons you need to buy?
Definition:

Real-world application: Using multiples to solve practical problems involving grouping and packaging.

Carton size: 12
Minimum needed: 50
Smallest multiple ≥ 50: 60
Step 1: List multiples of 12

12, 24, 36, 48, 60, 72...

Step 2: Find the first multiple ≥ 50

48 < 50 (too small)

60 ≥ 50 (this works!)

Step 3: Calculate cartons needed

60 ÷ 12 = 5 cartons

Step 4: Verify

5 × 12 = 60 eggs (≥ 50 ✓)

4 × 12 = 48 eggs (< 50 ✗)

Smallest number of cartons: 5
Answer:

5 cartons (60 eggs)

Applied rules:

• Problem solving: Translate words to mathematical operations

• Minimum requirement: Find smallest multiple ≥ target

• Practical application: Connect math to real situations

Questions & Answers

Question: How do I know if I'm ready for the advanced level questions?

Answer: You're ready for advanced questions when you can confidently:

  • Solve beginner questions quickly and accurately
  • Identify patterns in multiples and factors
  • Work with common multiples and least common multiples
  • Understand how to apply math to real-world situations

Start with beginner questions, move to intermediate once you're comfortable, then try advanced. Don't rush - mastering the basics is key!

If you can solve the intermediate questions with 80% accuracy, you're ready to try advanced!

Question: What should I do if I get stuck on a question during the test?

Answer: Here's what to do when stuck:

  1. Read the question again: Make sure you understand what's being asked
  2. Identify the concept: Is it about factors, multiples, or patterns?
  3. Try a simpler approach: Use smaller numbers to understand the pattern
  4. Move on and come back: Don't spend too long on one question
  5. Use scratch paper: Work out the problem step by step

Remember: It's better to answer easier questions first and return to harder ones later. Stay calm and think systematically!

Question: How can I check if my answers are correct?

Answer: Here are ways to verify your answers:

  • For multiples: Divide by the base number - should get a whole number
  • For factors: Multiply the factor pairs - should equal the original number
  • For common multiples: Check divisibility by both original numbers
  • For prime factors: Multiply all factors together - should equal original number

For example: If you say 12 is a multiple of 4, check: 12 ÷ 4 = 3 ✓. If you say 3 and 4 are factors of 12, check: 3 × 4 = 12 ✓.

Always take time to verify your answers when possible!
