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 26,167,031, 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 | 26,167,031 | |
| -1 | -26,167,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,167,031.
Example:
1 x 26,167,031 = 26,167,031
and
-1 x -26,167,031 = 26,167,031
Notice both answers equal 26,167,031
With that explanation out of the way, let's continue. Next, we take the number 26,167,031 and divide it by 2:
26,167,031 ÷ 2 = 13,083,515.5
If the quotient is a whole number, then 2 and 13,083,515.5 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 | 26,167,031 | |
| -1 | -26,167,031 |
Now, we try dividing 26,167,031 by 3:
26,167,031 ÷ 3 = 8,722,343.6667
If the quotient is a whole number, then 3 and 8,722,343.6667 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 | 26,167,031 | |
| -1 | -26,167,031 |
Let's try dividing by 4:
26,167,031 ÷ 4 = 6,541,757.75
If the quotient is a whole number, then 4 and 6,541,757.75 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 | 26,167,031 | |
| -1 | 26,167,031 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 59 | 253 | 649 | 1,357 | 1,753 | 14,927 | 19,283 | 40,319 | 103,427 | 443,509 | 1,137,697 | 2,378,821 | 26,167,031 |
| -1 | -11 | -23 | -59 | -253 | -649 | -1,357 | -1,753 | -14,927 | -19,283 | -40,319 | -103,427 | -443,509 | -1,137,697 | -2,378,821 | -26,167,031 |
