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 13,526,891, 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 | 13,526,891 | |
| -1 | -13,526,891 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,526,891.
Example:
1 x 13,526,891 = 13,526,891
and
-1 x -13,526,891 = 13,526,891
Notice both answers equal 13,526,891
With that explanation out of the way, let's continue. Next, we take the number 13,526,891 and divide it by 2:
13,526,891 ÷ 2 = 6,763,445.5
If the quotient is a whole number, then 2 and 6,763,445.5 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 | 13,526,891 | |
| -1 | -13,526,891 |
Now, we try dividing 13,526,891 by 3:
13,526,891 ÷ 3 = 4,508,963.6667
If the quotient is a whole number, then 3 and 4,508,963.6667 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 | 13,526,891 | |
| -1 | -13,526,891 |
Let's try dividing by 4:
13,526,891 ÷ 4 = 3,381,722.75
If the quotient is a whole number, then 4 and 3,381,722.75 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 | 13,526,891 | |
| -1 | 13,526,891 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 113 | 343 | 349 | 791 | 2,443 | 5,537 | 17,101 | 38,759 | 39,437 | 119,707 | 276,059 | 1,932,413 | 13,526,891 |
| -1 | -7 | -49 | -113 | -343 | -349 | -791 | -2,443 | -5,537 | -17,101 | -38,759 | -39,437 | -119,707 | -276,059 | -1,932,413 | -13,526,891 |
