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 40,472,117, 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 | 40,472,117 | |
| -1 | -40,472,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,472,117.
Example:
1 x 40,472,117 = 40,472,117
and
-1 x -40,472,117 = 40,472,117
Notice both answers equal 40,472,117
With that explanation out of the way, let's continue. Next, we take the number 40,472,117 and divide it by 2:
40,472,117 ÷ 2 = 20,236,058.5
If the quotient is a whole number, then 2 and 20,236,058.5 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 | 40,472,117 | |
| -1 | -40,472,117 |
Now, we try dividing 40,472,117 by 3:
40,472,117 ÷ 3 = 13,490,705.6667
If the quotient is a whole number, then 3 and 13,490,705.6667 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 | 40,472,117 | |
| -1 | -40,472,117 |
Let's try dividing by 4:
40,472,117 ÷ 4 = 10,118,029.25
If the quotient is a whole number, then 4 and 10,118,029.25 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 | 40,472,117 | |
| -1 | 40,472,117 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 307 | 509 | 2,149 | 3,563 | 11,359 | 18,833 | 79,513 | 131,831 | 156,263 | 1,093,841 | 5,781,731 | 40,472,117 |
| -1 | -7 | -37 | -259 | -307 | -509 | -2,149 | -3,563 | -11,359 | -18,833 | -79,513 | -131,831 | -156,263 | -1,093,841 | -5,781,731 | -40,472,117 |
