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 10,127,075, 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 | 10,127,075 | |
| -1 | -10,127,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,127,075.
Example:
1 x 10,127,075 = 10,127,075
and
-1 x -10,127,075 = 10,127,075
Notice both answers equal 10,127,075
With that explanation out of the way, let's continue. Next, we take the number 10,127,075 and divide it by 2:
10,127,075 ÷ 2 = 5,063,537.5
If the quotient is a whole number, then 2 and 5,063,537.5 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 | 10,127,075 | |
| -1 | -10,127,075 |
Now, we try dividing 10,127,075 by 3:
10,127,075 ÷ 3 = 3,375,691.6667
If the quotient is a whole number, then 3 and 3,375,691.6667 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 | 10,127,075 | |
| -1 | -10,127,075 |
Let's try dividing by 4:
10,127,075 ÷ 4 = 2,531,768.75
If the quotient is a whole number, then 4 and 2,531,768.75 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 | 10,127,075 | |
| -1 | 10,127,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 343 | 1,181 | 1,225 | 1,715 | 5,905 | 8,267 | 8,575 | 29,525 | 41,335 | 57,869 | 206,675 | 289,345 | 405,083 | 1,446,725 | 2,025,415 | 10,127,075 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -343 | -1,181 | -1,225 | -1,715 | -5,905 | -8,267 | -8,575 | -29,525 | -41,335 | -57,869 | -206,675 | -289,345 | -405,083 | -1,446,725 | -2,025,415 | -10,127,075 |
