Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 28,550,275, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 28,550,275 | |
| -1 | -28,550,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,550,275.
Example:
1 x 28,550,275 = 28,550,275
and
-1 x -28,550,275 = 28,550,275
Notice both answers equal 28,550,275
With that explanation out of the way, let's continue. Next, we take the number 28,550,275 and divide it by 2:
28,550,275 ÷ 2 = 14,275,137.5
If the quotient is a whole number, then 2 and 14,275,137.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 28,550,275 | |
| -1 | -28,550,275 |
Now, we try dividing 28,550,275 by 3:
28,550,275 ÷ 3 = 9,516,758.3333
If the quotient is a whole number, then 3 and 9,516,758.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 28,550,275 | |
| -1 | -28,550,275 |
Let's try dividing by 4:
28,550,275 ÷ 4 = 7,137,568.75
If the quotient is a whole number, then 4 and 7,137,568.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 28,550,275 | |
| -1 | 28,550,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 107 | 325 | 535 | 821 | 1,391 | 2,675 | 4,105 | 6,955 | 10,673 | 20,525 | 34,775 | 53,365 | 87,847 | 266,825 | 439,235 | 1,142,011 | 2,196,175 | 5,710,055 | 28,550,275 |
| -1 | -5 | -13 | -25 | -65 | -107 | -325 | -535 | -821 | -1,391 | -2,675 | -4,105 | -6,955 | -10,673 | -20,525 | -34,775 | -53,365 | -87,847 | -266,825 | -439,235 | -1,142,011 | -2,196,175 | -5,710,055 | -28,550,275 |
