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 10,902,125, 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 | 10,902,125 | |
| -1 | -10,902,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,902,125.
Example:
1 x 10,902,125 = 10,902,125
and
-1 x -10,902,125 = 10,902,125
Notice both answers equal 10,902,125
With that explanation out of the way, let's continue. Next, we take the number 10,902,125 and divide it by 2:
10,902,125 ÷ 2 = 5,451,062.5
If the quotient is a whole number, then 2 and 5,451,062.5 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 | 10,902,125 | |
| -1 | -10,902,125 |
Now, we try dividing 10,902,125 by 3:
10,902,125 ÷ 3 = 3,634,041.6667
If the quotient is a whole number, then 3 and 3,634,041.6667 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 | 10,902,125 | |
| -1 | -10,902,125 |
Let's try dividing by 4:
10,902,125 ÷ 4 = 2,725,531.25
If the quotient is a whole number, then 4 and 2,725,531.25 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 | 10,902,125 | |
| -1 | 10,902,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 1,625 | 6,709 | 33,545 | 87,217 | 167,725 | 436,085 | 838,625 | 2,180,425 | 10,902,125 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -1,625 | -6,709 | -33,545 | -87,217 | -167,725 | -436,085 | -838,625 | -2,180,425 | -10,902,125 |
