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 10,111,325, 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 | 10,111,325 | |
| -1 | -10,111,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,111,325.
Example:
1 x 10,111,325 = 10,111,325
and
-1 x -10,111,325 = 10,111,325
Notice both answers equal 10,111,325
With that explanation out of the way, let's continue. Next, we take the number 10,111,325 and divide it by 2:
10,111,325 ÷ 2 = 5,055,662.5
If the quotient is a whole number, then 2 and 5,055,662.5 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 | 10,111,325 | |
| -1 | -10,111,325 |
Now, we try dividing 10,111,325 by 3:
10,111,325 ÷ 3 = 3,370,441.6667
If the quotient is a whole number, then 3 and 3,370,441.6667 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 | 10,111,325 | |
| -1 | -10,111,325 |
Let's try dividing by 4:
10,111,325 ÷ 4 = 2,527,831.25
If the quotient is a whole number, then 4 and 2,527,831.25 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 | 10,111,325 | |
| -1 | 10,111,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 25 | 35 | 95 | 133 | 175 | 475 | 665 | 3,041 | 3,325 | 15,205 | 21,287 | 57,779 | 76,025 | 106,435 | 288,895 | 404,453 | 532,175 | 1,444,475 | 2,022,265 | 10,111,325 |
| -1 | -5 | -7 | -19 | -25 | -35 | -95 | -133 | -175 | -475 | -665 | -3,041 | -3,325 | -15,205 | -21,287 | -57,779 | -76,025 | -106,435 | -288,895 | -404,453 | -532,175 | -1,444,475 | -2,022,265 | -10,111,325 |
