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 8,512,427, 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 | 8,512,427 | |
| -1 | -8,512,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,512,427.
Example:
1 x 8,512,427 = 8,512,427
and
-1 x -8,512,427 = 8,512,427
Notice both answers equal 8,512,427
With that explanation out of the way, let's continue. Next, we take the number 8,512,427 and divide it by 2:
8,512,427 ÷ 2 = 4,256,213.5
If the quotient is a whole number, then 2 and 4,256,213.5 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 | 8,512,427 | |
| -1 | -8,512,427 |
Now, we try dividing 8,512,427 by 3:
8,512,427 ÷ 3 = 2,837,475.6667
If the quotient is a whole number, then 3 and 2,837,475.6667 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 | 8,512,427 | |
| -1 | -8,512,427 |
Let's try dividing by 4:
8,512,427 ÷ 4 = 2,128,106.75
If the quotient is a whole number, then 4 and 2,128,106.75 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 | 8,512,427 | |
| -1 | 8,512,427 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 49 | 77 | 119 | 187 | 539 | 833 | 929 | 1,309 | 6,503 | 9,163 | 10,219 | 15,793 | 45,521 | 71,533 | 110,551 | 173,723 | 500,731 | 773,857 | 1,216,061 | 8,512,427 |
| -1 | -7 | -11 | -17 | -49 | -77 | -119 | -187 | -539 | -833 | -929 | -1,309 | -6,503 | -9,163 | -10,219 | -15,793 | -45,521 | -71,533 | -110,551 | -173,723 | -500,731 | -773,857 | -1,216,061 | -8,512,427 |
