The multiplication value of two quantities is 1440, and their highest common factor (HCF) is 18. Determine their least common multiple (LCM).
80
For any two numbers, the product of the numbers equals the product of their HCF and LCM: \(\text{Product} = \text{HCF} \times \text{LCM}\).
Substituting the given values: \(1440 = 18 \times \text{LCM}\).
So \(\text{LCM} = \dfrac{1440}{18} = 80\).
