First, you must find all of the positive factors of 180; they are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, and 180. Next, you must add them all. After completing all of these steps, you will find that their sum is 546.
The odd positive integer factors of 70 are: 1 5 7 35 The sum of these factors is 1 + 5 + 7 + 35 = 48
All of the [positive] whole-number factors of 24 are: 1, 2, 3, 4, 6, 8, 12, and 24. Their sum is 60.

The odd positive integer factors of 70 are: 1 5 7 35 The sum of these factors is 1 + 5 + 7 + 35 = 48
45 and 12.
Any set of three different positive numbers that sum to 180.
All of the [positive] whole-number factors of 24 are: 1, 2, 3, 4, 6, 8, 12, and 24. Their sum is 60.

Each angle theta is (n-2)/n) x 180 degrees The sum of all angles is nx theta = (n-2) x 180 sum = 180 n - 360 sum + 360 = 180 n n = (sum + 360)/180 = sum/180 + 2 So you divide sum by 180 then add 2
