# If possible, find a hook-up of prime base number machine that will do the same work as the given stretching machine. Do not use (× 1) machines. (figure c)

**Solution:**

Given, the figure represents a single machine.

We have to find a hook-up of prime base number machine that will do the same work as the given stretching machine.

Total work of the single machine = ×37

The __prime factors__ of 37 = 1 × 37

Since, it is mentioned not to use 1.

No machines can be hooked up to produce the same work.
