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 12,571,349, 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 | 12,571,349 | |
| -1 | -12,571,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,571,349.
Example:
1 x 12,571,349 = 12,571,349
and
-1 x -12,571,349 = 12,571,349
Notice both answers equal 12,571,349
With that explanation out of the way, let's continue. Next, we take the number 12,571,349 and divide it by 2:
12,571,349 ÷ 2 = 6,285,674.5
If the quotient is a whole number, then 2 and 6,285,674.5 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 | 12,571,349 | |
| -1 | -12,571,349 |
Now, we try dividing 12,571,349 by 3:
12,571,349 ÷ 3 = 4,190,449.6667
If the quotient is a whole number, then 3 and 4,190,449.6667 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 | 12,571,349 | |
| -1 | -12,571,349 |
Let's try dividing by 4:
12,571,349 ÷ 4 = 3,142,837.25
If the quotient is a whole number, then 4 and 3,142,837.25 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 | 12,571,349 | |
| -1 | 12,571,349 |
If you did it right, you will end up with this table:
| 1 | 7 | 79 | 127 | 179 | 553 | 889 | 1,253 | 10,033 | 14,141 | 22,733 | 70,231 | 98,987 | 159,131 | 1,795,907 | 12,571,349 |
| -1 | -7 | -79 | -127 | -179 | -553 | -889 | -1,253 | -10,033 | -14,141 | -22,733 | -70,231 | -98,987 | -159,131 | -1,795,907 | -12,571,349 |
