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 10,230,325, 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 | 10,230,325 | |
| -1 | -10,230,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,230,325.
Example:
1 x 10,230,325 = 10,230,325
and
-1 x -10,230,325 = 10,230,325
Notice both answers equal 10,230,325
With that explanation out of the way, let's continue. Next, we take the number 10,230,325 and divide it by 2:
10,230,325 ÷ 2 = 5,115,162.5
If the quotient is a whole number, then 2 and 5,115,162.5 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 | 10,230,325 | |
| -1 | -10,230,325 |
Now, we try dividing 10,230,325 by 3:
10,230,325 ÷ 3 = 3,410,108.3333
If the quotient is a whole number, then 3 and 3,410,108.3333 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 | 10,230,325 | |
| -1 | -10,230,325 |
Let's try dividing by 4:
10,230,325 ÷ 4 = 2,557,581.25
If the quotient is a whole number, then 4 and 2,557,581.25 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 | 10,230,325 | |
| -1 | 10,230,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 53 | 175 | 265 | 371 | 1,103 | 1,325 | 1,855 | 5,515 | 7,721 | 9,275 | 27,575 | 38,605 | 58,459 | 193,025 | 292,295 | 409,213 | 1,461,475 | 2,046,065 | 10,230,325 |
| -1 | -5 | -7 | -25 | -35 | -53 | -175 | -265 | -371 | -1,103 | -1,325 | -1,855 | -5,515 | -7,721 | -9,275 | -27,575 | -38,605 | -58,459 | -193,025 | -292,295 | -409,213 | -1,461,475 | -2,046,065 | -10,230,325 |
