With the software you can use the perimeter circle option (in SW) OR TTT option in 2d Cad software.

For hand, check this: Tangent Circles

Try this:

Given three circles with non-collinear centers:

Draw lines connecting the centers of the three circles.

Locate the midpoints of these lines

draw lines perpendicular to the connecting lines at the their midpoints.

The intersections of these connecting lines is the center of your tangent circle.

Extend one of the connecting lines through the diameter of it's circle. The point where the extension crosses the perimeter of it's circle is a point on the radius of your solution circle

Sweep an arc with your compass pinned to the derived center, passing the other end through the derived radial point.

What do you mean without using software? Are you looking to draw it on paper?
