The equation given is:

\[
x^2 - 7x + 12 = 0
\]

We need to solve this by factoring. The goal is to factor the quadratic expression into two binomials. We are looking for two numbers that multiply to give the constant term \( 12 \) and add to give the coefficient of the middle term \( -7 \).

The pair of numbers that satisfy this condition are \( -3 \) and \( -4 \), since:

\[
(-3) \times (-4) = 12 \quad \text{and} \quad (-3) + (-4) = -7
\]

Thus, the factored form of the equation is:

\[
(x - 3)(x - 4) = 0
\]

Setting each factor equal to zero gives:

\[
x - 3 = 0 \quad \text{or} \quad x - 4 = 0
\]

So, the solutions are:

\[
x = 3 \quad \text{and} \quad x = 4
\]

Since the problem asks for the smallest solution first, the answer is:

\[
x = 3, 4
\]
