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 9,250,087, 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 | 9,250,087 | |
| -1 | -9,250,087 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,250,087.
Example:
1 x 9,250,087 = 9,250,087
and
-1 x -9,250,087 = 9,250,087
Notice both answers equal 9,250,087
With that explanation out of the way, let's continue. Next, we take the number 9,250,087 and divide it by 2:
9,250,087 ÷ 2 = 4,625,043.5
If the quotient is a whole number, then 2 and 4,625,043.5 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 | 9,250,087 | |
| -1 | -9,250,087 |
Now, we try dividing 9,250,087 by 3:
9,250,087 ÷ 3 = 3,083,362.3333
If the quotient is a whole number, then 3 and 3,083,362.3333 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 | 9,250,087 | |
| -1 | -9,250,087 |
Let's try dividing by 4:
9,250,087 ÷ 4 = 2,312,521.75
If the quotient is a whole number, then 4 and 2,312,521.75 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 | 9,250,087 | |
| -1 | 9,250,087 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 67 | 77 | 121 | 163 | 469 | 737 | 847 | 1,141 | 1,793 | 5,159 | 8,107 | 10,921 | 12,551 | 19,723 | 56,749 | 76,447 | 120,131 | 138,061 | 840,917 | 1,321,441 | 9,250,087 |
| -1 | -7 | -11 | -67 | -77 | -121 | -163 | -469 | -737 | -847 | -1,141 | -1,793 | -5,159 | -8,107 | -10,921 | -12,551 | -19,723 | -56,749 | -76,447 | -120,131 | -138,061 | -840,917 | -1,321,441 | -9,250,087 |
