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 10,252,145, 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 | 10,252,145 | |
| -1 | -10,252,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,252,145.
Example:
1 x 10,252,145 = 10,252,145
and
-1 x -10,252,145 = 10,252,145
Notice both answers equal 10,252,145
With that explanation out of the way, let's continue. Next, we take the number 10,252,145 and divide it by 2:
10,252,145 ÷ 2 = 5,126,072.5
If the quotient is a whole number, then 2 and 5,126,072.5 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 | 10,252,145 | |
| -1 | -10,252,145 |
Now, we try dividing 10,252,145 by 3:
10,252,145 ÷ 3 = 3,417,381.6667
If the quotient is a whole number, then 3 and 3,417,381.6667 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 | 10,252,145 | |
| -1 | -10,252,145 |
Let's try dividing by 4:
10,252,145 ÷ 4 = 2,563,036.25
If the quotient is a whole number, then 4 and 2,563,036.25 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 | 10,252,145 | |
| -1 | 10,252,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 151 | 185 | 367 | 755 | 1,835 | 5,587 | 13,579 | 27,935 | 55,417 | 67,895 | 277,085 | 2,050,429 | 10,252,145 |
| -1 | -5 | -37 | -151 | -185 | -367 | -755 | -1,835 | -5,587 | -13,579 | -27,935 | -55,417 | -67,895 | -277,085 | -2,050,429 | -10,252,145 |
