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 39,475,415, 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 | 39,475,415 | |
| -1 | -39,475,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 39,475,415.
Example:
1 x 39,475,415 = 39,475,415
and
-1 x -39,475,415 = 39,475,415
Notice both answers equal 39,475,415
With that explanation out of the way, let's continue. Next, we take the number 39,475,415 and divide it by 2:
39,475,415 ÷ 2 = 19,737,707.5
If the quotient is a whole number, then 2 and 19,737,707.5 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 | 39,475,415 | |
| -1 | -39,475,415 |
Now, we try dividing 39,475,415 by 3:
39,475,415 ÷ 3 = 13,158,471.6667
If the quotient is a whole number, then 3 and 13,158,471.6667 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 | 39,475,415 | |
| -1 | -39,475,415 |
Let's try dividing by 4:
39,475,415 ÷ 4 = 9,868,853.75
If the quotient is a whole number, then 4 and 9,868,853.75 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 | 39,475,415 | |
| -1 | 39,475,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 205 | 287 | 1,435 | 27,509 | 137,545 | 192,563 | 962,815 | 1,127,869 | 5,639,345 | 7,895,083 | 39,475,415 |
| -1 | -5 | -7 | -35 | -41 | -205 | -287 | -1,435 | -27,509 | -137,545 | -192,563 | -962,815 | -1,127,869 | -5,639,345 | -7,895,083 | -39,475,415 |
