1. **Problem:** Find the Least Common Multiple (LCM) or KPK of 8, 12, and 18. 2. **Formula and rules:** - Prime factorize each number. - LCM is found by taking the highest powers of all prime factors involved. 3. **Prime factorization:** - $8 = 2^3$ - $12 = 2^2 \times 3$ - $18 = 2 \times 3^2$ 4. **Calculate LCM:** - Take highest powers: $2^3$ (from 8) and $3^2$ (from 18) - Multiply: $$2^3 \times 3^2 = 8 \times 9 = 72$$ 5. **Answer:** The LCM (KPK) of 8, 12, and 18 is **72**.
