Standardizing Technical Formulas Using the LCD

A technical analyst is merging two algebraic models that utilize the rational expressions 2x2−x−12\frac{2}{x^2 - x - 12} and 1x2−16\frac{1}{x^2 - 16}. To align the formulas, the analyst identifies the factored forms of the denominators as (x−4)(x+3)(x - 4)(x + 3) and (x−4)(x+4)(x - 4)(x + 4). Based on these factors, what is the complete, factored form of the Least Common Denominator (LCD) for these two expressions?
