#### Answer

$19$

#### Work Step by Step

The product of two numbers with the same sign can be found by performing the following steps:
(1) Multiply their absolute values.
$|-19| \cdot |-1| = 19 \cdot 1 = 19$
(2) The product is positive.
$-19(-1) = 19$
Thus, the product of the given numbers is $19$.
