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 26,125,171, 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 | 26,125,171 | |
| -1 | -26,125,171 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,125,171.
Example:
1 x 26,125,171 = 26,125,171
and
-1 x -26,125,171 = 26,125,171
Notice both answers equal 26,125,171
With that explanation out of the way, let's continue. Next, we take the number 26,125,171 and divide it by 2:
26,125,171 ÷ 2 = 13,062,585.5
If the quotient is a whole number, then 2 and 13,062,585.5 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 | 26,125,171 | |
| -1 | -26,125,171 |
Now, we try dividing 26,125,171 by 3:
26,125,171 ÷ 3 = 8,708,390.3333
If the quotient is a whole number, then 3 and 8,708,390.3333 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 | 26,125,171 | |
| -1 | -26,125,171 |
Let's try dividing by 4:
26,125,171 ÷ 4 = 6,531,292.75
If the quotient is a whole number, then 4 and 6,531,292.75 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 | 26,125,171 | |
| -1 | 26,125,171 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 191 | 313 | 437 | 3,629 | 4,393 | 5,947 | 7,199 | 59,783 | 83,467 | 136,781 | 1,135,877 | 1,375,009 | 26,125,171 |
| -1 | -19 | -23 | -191 | -313 | -437 | -3,629 | -4,393 | -5,947 | -7,199 | -59,783 | -83,467 | -136,781 | -1,135,877 | -1,375,009 | -26,125,171 |
