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 10,176,725, 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 | 10,176,725 | |
| -1 | -10,176,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,176,725.
Example:
1 x 10,176,725 = 10,176,725
and
-1 x -10,176,725 = 10,176,725
Notice both answers equal 10,176,725
With that explanation out of the way, let's continue. Next, we take the number 10,176,725 and divide it by 2:
10,176,725 ÷ 2 = 5,088,362.5
If the quotient is a whole number, then 2 and 5,088,362.5 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 | 10,176,725 | |
| -1 | -10,176,725 |
Now, we try dividing 10,176,725 by 3:
10,176,725 ÷ 3 = 3,392,241.6667
If the quotient is a whole number, then 3 and 3,392,241.6667 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 | 10,176,725 | |
| -1 | -10,176,725 |
Let's try dividing by 4:
10,176,725 ÷ 4 = 2,544,181.25
If the quotient is a whole number, then 4 and 2,544,181.25 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 | 10,176,725 | |
| -1 | 10,176,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 173 | 181 | 325 | 865 | 905 | 2,249 | 2,353 | 4,325 | 4,525 | 11,245 | 11,765 | 31,313 | 56,225 | 58,825 | 156,565 | 407,069 | 782,825 | 2,035,345 | 10,176,725 |
| -1 | -5 | -13 | -25 | -65 | -173 | -181 | -325 | -865 | -905 | -2,249 | -2,353 | -4,325 | -4,525 | -11,245 | -11,765 | -31,313 | -56,225 | -58,825 | -156,565 | -407,069 | -782,825 | -2,035,345 | -10,176,725 |
