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 2,850,925, 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 | 2,850,925 | |
| -1 | -2,850,925 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,850,925.
Example:
1 x 2,850,925 = 2,850,925
and
-1 x -2,850,925 = 2,850,925
Notice both answers equal 2,850,925
With that explanation out of the way, let's continue. Next, we take the number 2,850,925 and divide it by 2:
2,850,925 ÷ 2 = 1,425,462.5
If the quotient is a whole number, then 2 and 1,425,462.5 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 | 2,850,925 | |
| -1 | -2,850,925 |
Now, we try dividing 2,850,925 by 3:
2,850,925 ÷ 3 = 950,308.3333
If the quotient is a whole number, then 3 and 950,308.3333 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 | 2,850,925 | |
| -1 | -2,850,925 |
Let's try dividing by 4:
2,850,925 ÷ 4 = 712,731.25
If the quotient is a whole number, then 4 and 712,731.25 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 | 2,850,925 | |
| -1 | 2,850,925 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 1,481 | 1,925 | 7,405 | 10,367 | 16,291 | 37,025 | 51,835 | 81,455 | 114,037 | 259,175 | 407,275 | 570,185 | 2,850,925 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -1,481 | -1,925 | -7,405 | -10,367 | -16,291 | -37,025 | -51,835 | -81,455 | -114,037 | -259,175 | -407,275 | -570,185 | -2,850,925 |
