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 267,257,107, 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 | 267,257,107 | |
| -1 | -267,257,107 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 267,257,107.
Example:
1 x 267,257,107 = 267,257,107
and
-1 x -267,257,107 = 267,257,107
Notice both answers equal 267,257,107
With that explanation out of the way, let's continue. Next, we take the number 267,257,107 and divide it by 2:
267,257,107 ÷ 2 = 133,628,553.5
If the quotient is a whole number, then 2 and 133,628,553.5 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 | 267,257,107 | |
| -1 | -267,257,107 |
Now, we try dividing 267,257,107 by 3:
267,257,107 ÷ 3 = 89,085,702.3333
If the quotient is a whole number, then 3 and 89,085,702.3333 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 | 267,257,107 | |
| -1 | -267,257,107 |
Let's try dividing by 4:
267,257,107 ÷ 4 = 66,814,276.75
If the quotient is a whole number, then 4 and 66,814,276.75 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 | 267,257,107 | |
| -1 | 267,257,107 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 139 | 169 | 367 | 403 | 1,807 | 4,309 | 4,771 | 5,239 | 11,377 | 23,491 | 51,013 | 56,017 | 62,023 | 147,901 | 663,169 | 728,221 | 1,581,403 | 1,922,713 | 8,621,197 | 20,558,239 | 267,257,107 |
| -1 | -13 | -31 | -139 | -169 | -367 | -403 | -1,807 | -4,309 | -4,771 | -5,239 | -11,377 | -23,491 | -51,013 | -56,017 | -62,023 | -147,901 | -663,169 | -728,221 | -1,581,403 | -1,922,713 | -8,621,197 | -20,558,239 | -267,257,107 |
