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 26,271,725, 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 | 26,271,725 | |
| -1 | -26,271,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,271,725.
Example:
1 x 26,271,725 = 26,271,725
and
-1 x -26,271,725 = 26,271,725
Notice both answers equal 26,271,725
With that explanation out of the way, let's continue. Next, we take the number 26,271,725 and divide it by 2:
26,271,725 ÷ 2 = 13,135,862.5
If the quotient is a whole number, then 2 and 13,135,862.5 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 | 26,271,725 | |
| -1 | -26,271,725 |
Now, we try dividing 26,271,725 by 3:
26,271,725 ÷ 3 = 8,757,241.6667
If the quotient is a whole number, then 3 and 8,757,241.6667 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 | 26,271,725 | |
| -1 | -26,271,725 |
Let's try dividing by 4:
26,271,725 ÷ 4 = 6,567,931.25
If the quotient is a whole number, then 4 and 6,567,931.25 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 | 26,271,725 | |
| -1 | 26,271,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 109 | 155 | 311 | 545 | 775 | 1,555 | 2,725 | 3,379 | 7,775 | 9,641 | 16,895 | 33,899 | 48,205 | 84,475 | 169,495 | 241,025 | 847,475 | 1,050,869 | 5,254,345 | 26,271,725 |
| -1 | -5 | -25 | -31 | -109 | -155 | -311 | -545 | -775 | -1,555 | -2,725 | -3,379 | -7,775 | -9,641 | -16,895 | -33,899 | -48,205 | -84,475 | -169,495 | -241,025 | -847,475 | -1,050,869 | -5,254,345 | -26,271,725 |
