To find four numbers that equal 140, one possible combination is 35, 35, 35, and 35. Another combination could be 50, 40, 30, and 20. You can also use negative numbers, such as 100, 50, -10, and 0. The key is that the sum of the four selected numbers must equal 140.
To find four numbers that multiply to 140, one possible combination is 1, 2, 5, and 14, since (1 \times 2 \times 5 \times 14 = 140). Another combination could be 2, 5, 2, and 7, as (2 \times 5 \times 2 \times 7 = 140). There are various combinations possible, but these are a couple of examples.

There are infinitely many pairs. The simplest is 1 and 140.
2 x 2 x 5 x 7 = 140
To find four numbers that multiply to 140, one possible combination is 1, 2, 5, and 14, since (1 \times 2 \times 5 \times 14 = 140). Another combination could be 2, 5, 2, and 7, as (2 \times 5 \times 2 \times 7 = 140). There are various combinations possible, but these are a couple of examples.
140 + 20 + 6 = 166.
