    ---

    Basic Questions:

26. HCF of 24 and 36 = 12

27. LCM of 15 and 20 = 60

28. HCF × LCM = Product of numbers → $12 \times 180 = 36 \times x$ → $x = 60$

29. HCF of 72, 108, 144 = 36

30. LCM of 8, 12, and 15 = 120

31. HCF × LCM = Product of numbers → $6 \times 120 = 30 \times x$ → $x = 24$

32. Possible LCMs: Any multiple of (50 ÷ 5) = 10, so possible LCM = 10, 20, 30, etc.

33. LCM of first five prime numbers (2,3,5,7,11) = 2310

34. HCF of 120 and 180 (Prime factorization method): $120 = 2^3 \times 3 \times 5$, $180 = 2^2 \times 3^2 \times 5$ → HCF = $2^2 \times 3 \times 5 = 60$

35. LCM = (Product of numbers) / HCF → $540 / 6 = 90$

Intermediate-Level Questions:

11. LCM = (Product of numbers) / HCF → $(16 × 28) / 4 = 112$

12. HCF of two co-prime numbers is always 1.

13. HCF × LCM = Product of numbers → $3 \times 252 = 9 \times 14 \times x$ → $x = 6$

14. LCM of 9, 12, 18 = 36

15. HCF of 72 and 90 (Using prime factorization) = 18

16. LCM of 4, 6, and 8 = 24 minutes

17. Product of two numbers = HCF × LCM → $18 \times 540 = 9720$

18. Other number = (LCM × HCF) / Given number → $(84 × 4) / 12 = 28$

19. LCM of 6, 9, and 15 = 90, adding remainder 3 → 93

20. LCM = (Product of numbers) / HCF → $168 / 4 = 42$

---

Advanced-Level Questions:

21. HCF of 125, 150, and 200 = 25

22. LCM of 4, 5, and 6 = 60, required number = 60 × k + 3 (Check divisibility by 7) → Smallest number = 123

23. HCF of 36, 48, 60 (to divide into equal rows) = 12 rows

24. LCM of fractions = LCM (Numerators) / HCF (Denominators)

• LCM of 2, 3, 5 = 30

• HCF of 3, 4, 6 = 1

• LCM = 30/1 = 30

25. HCF of fractions = HCF (Numerators) / LCM (Denominators)

• HCF of 8, 12, 16 = 4

• LCM of 9, 15, 25 = 225

• HCF = 4/225
