Step 1.2.1

Raise $a$ to the power of $1$ .

$\frac{a \cdot a}{a} \cdot \frac{1}{a}$

Step 1.2.2

Factor $a$ out of $a^{1}$ .

$\frac{a \cdot a}{a \cdot 1} \cdot \frac{1}{a}$

Step 1.2.3

Cancel the common factor.

$\frac{a \cdot a}{a \cdot 1} \cdot \frac{1}{a}$

Step 1.2.4

Rewrite the expression.

$\frac{a}{1} \cdot \frac{1}{a}$

Step 1.2.5

Divide $a$ by $1$ .

$a \cdot \frac{1}{a}$

Step 2

Finding the LCD of a list of values is the same as finding the LCM of the denominators of those values.

$1, a$

Step 3

The LCM of one and any expression is the expression.

$a$
