Finding HCF
We express each number as the product of 1 and prime numbers:
- 3 = 1 × 3
- 6 = 1 × 2 × 3
- 9 = 1 × 3 × 3
- 12 = 1 × 2 × 2 × 3
- 15 = 1 × 3 × 5
- 18 = 1 × 2 × 3 × 3
- 24 = 1 × 2 × 2 × 2 × 3
- 30 = 1 × 2 × 3 × 5
- 36 = 1 × 2 × 2 × 3 × 3
Now we find HCF of given pairs:
- HCF(12, 3) = 1 × 3 = 3
- HCF(15, 3) = 1 × 3 = 3
- HCF(18, 3) = 1 × 3 = 3
- HCF(30, 3) = 1 × 3 = 3
- HCF(36, 3) = 1 × 3 = 3
- HCF(12, 6) = 1 × 2 × 3 = 6
- HCF(15, 6) = 1 × 3 = 3
- HCF(18, 6) = 1 × 2 × 3 = 6
- HCF(30, 6) = 1 × 2 × 3 = 6
- HCF(36, 6) = 1 × 2 × 3 = 6
- HCF(12, 9) = 1 × 3 = 3
- HCF(15, 9) = 1 × 3 = 3
- HCF(18, 9) = 1 × 3 × 3 = 9
- HCF(30, 9) = 1 × 3 = 3
- HCF(36, 9) = 1 × 3 × 3 = 9
- HCF(12, 12) = 1 × 2 × 2 × 3 = 12
- HCF(15, 12) = 1 × 3 = 3
- HCF(18, 12) = 1 × 2 × 3 = 6
- HCF(30, 12) = 1 × 2 × 3 = 6
- HCF(36, 12) = 1 × 2 × 2 × 3 = 12
- HCF(12, 24) = 1 × 2 × 2 × 3 = 12
- HCF(15, 24) = 1 × 3 = 3
- HCF(18, 24) = 1 × 2 × 3 = 6
- HCF(30, 24) = 1 × 2 × 3 = 6
- HCF(36, 24) = 1 × 2 × 2 × 3 = 12
