WebFeb 2, 2024 · You can calculate the LCD from the Greatest Common Factor (GCF) (as in our GCF calculator) value: LCD (a,b) = a * b / GCF (a,b) where a * b is the absolute value of a * b. Substitute the first two numbers (2 and 8) into the formula: LCD (2, 8) = 2 * 8 / GCF (2, 8). We know that GCF (2, 8) = 2 so: LCD (2, 8) = 16 / 2 = 8 WebWhen adding or subtracting rational expressions, you need have common denominators just like any other fraction.
