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 10,015,159, 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 | 10,015,159 | |
| -1 | -10,015,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,015,159.
Example:
1 x 10,015,159 = 10,015,159
and
-1 x -10,015,159 = 10,015,159
Notice both answers equal 10,015,159
With that explanation out of the way, let's continue. Next, we take the number 10,015,159 and divide it by 2:
10,015,159 ÷ 2 = 5,007,579.5
If the quotient is a whole number, then 2 and 5,007,579.5 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 | 10,015,159 | |
| -1 | -10,015,159 |
Now, we try dividing 10,015,159 by 3:
10,015,159 ÷ 3 = 3,338,386.3333
If the quotient is a whole number, then 3 and 3,338,386.3333 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 | 10,015,159 | |
| -1 | -10,015,159 |
Let's try dividing by 4:
10,015,159 ÷ 4 = 2,503,789.75
If the quotient is a whole number, then 4 and 2,503,789.75 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 | 10,015,159 | |
| -1 | 10,015,159 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 49 | 77 | 119 | 187 | 539 | 833 | 1,093 | 1,309 | 7,651 | 9,163 | 12,023 | 18,581 | 53,557 | 84,161 | 130,067 | 204,391 | 589,127 | 910,469 | 1,430,737 | 10,015,159 |
| -1 | -7 | -11 | -17 | -49 | -77 | -119 | -187 | -539 | -833 | -1,093 | -1,309 | -7,651 | -9,163 | -12,023 | -18,581 | -53,557 | -84,161 | -130,067 | -204,391 | -589,127 | -910,469 | -1,430,737 | -10,015,159 |
