If the HCF (Highest Common Factor) of two numbers is 4, then both numbers must be divisible by 4. One number is already given as 24, and we are to find other numbers that share 4 as their greatest common factor with 24.Factors of 24: 4, 8, 12, 16, 20, 24, etc.We just need to pick numbers that share 4 as the highest (not just any) common factor with 24.✅ 4 — common factors with 24: 1, 2, 4 → HCF = 4✅ 8 — common factors with 24: 1, 2, 4, 8 → HCF = 4⛔ 12 is not valid because HCF(24, 12) = 12⛔ 16 is not valid because HCF(24, 16) = 8So, possible values: 4 and 8Let me know if you need more help!
