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 26,431,141, 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 | 26,431,141 | |
| -1 | -26,431,141 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,431,141.
Example:
1 x 26,431,141 = 26,431,141
and
-1 x -26,431,141 = 26,431,141
Notice both answers equal 26,431,141
With that explanation out of the way, let's continue. Next, we take the number 26,431,141 and divide it by 2:
26,431,141 ÷ 2 = 13,215,570.5
If the quotient is a whole number, then 2 and 13,215,570.5 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 | 26,431,141 | |
| -1 | -26,431,141 |
Now, we try dividing 26,431,141 by 3:
26,431,141 ÷ 3 = 8,810,380.3333
If the quotient is a whole number, then 3 and 8,810,380.3333 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 | 26,431,141 | |
| -1 | -26,431,141 |
Let's try dividing by 4:
26,431,141 ÷ 4 = 6,607,785.25
If the quotient is a whole number, then 4 and 6,607,785.25 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 | 26,431,141 | |
| -1 | 26,431,141 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 281 | 503 | 3,091 | 4,777 | 5,533 | 8,551 | 52,547 | 94,061 | 141,343 | 1,554,773 | 2,402,831 | 26,431,141 |
| -1 | -11 | -17 | -187 | -281 | -503 | -3,091 | -4,777 | -5,533 | -8,551 | -52,547 | -94,061 | -141,343 | -1,554,773 | -2,402,831 | -26,431,141 |
