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 10,010,645, 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 | 10,010,645 | |
| -1 | -10,010,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,010,645.
Example:
1 x 10,010,645 = 10,010,645
and
-1 x -10,010,645 = 10,010,645
Notice both answers equal 10,010,645
With that explanation out of the way, let's continue. Next, we take the number 10,010,645 and divide it by 2:
10,010,645 ÷ 2 = 5,005,322.5
If the quotient is a whole number, then 2 and 5,005,322.5 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 | 10,010,645 | |
| -1 | -10,010,645 |
Now, we try dividing 10,010,645 by 3:
10,010,645 ÷ 3 = 3,336,881.6667
If the quotient is a whole number, then 3 and 3,336,881.6667 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 | 10,010,645 | |
| -1 | -10,010,645 |
Let's try dividing by 4:
10,010,645 ÷ 4 = 2,502,661.25
If the quotient is a whole number, then 4 and 2,502,661.25 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 | 10,010,645 | |
| -1 | 10,010,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 163 | 173 | 355 | 815 | 865 | 11,573 | 12,283 | 28,199 | 57,865 | 61,415 | 140,995 | 2,002,129 | 10,010,645 |
| -1 | -5 | -71 | -163 | -173 | -355 | -815 | -865 | -11,573 | -12,283 | -28,199 | -57,865 | -61,415 | -140,995 | -2,002,129 | -10,010,645 |
