The reduce() function in Python is a built-in function that applies a binary operator to an iterable (list, tuple etc.) in a cumulative way. We can use this function to multiply all elements of a list.

1. Import the Reduce Function
``````from functools import reduce
``````
2. Define List and Apply Multiplication
``````numbers = [1, 2, 3, 4, 5] # Your list here
product = reduce((lambda x, y: x * y), numbers)
print(product)
``````

In this code, the lambda function is used to define a multiplication operation and it’s applied to all elements of `numbers` in turn using the `reduce()` function. The result will be printed as the product of all elements in the list.

This solution works because the binary operator (`*`) is associative, meaning the order in which you perform operations does not affect the final result, and thus it can be applied cumulatively.
