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 40,887,601, 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 | 40,887,601 | |
| -1 | -40,887,601 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,887,601.
Example:
1 x 40,887,601 = 40,887,601
and
-1 x -40,887,601 = 40,887,601
Notice both answers equal 40,887,601
With that explanation out of the way, let's continue. Next, we take the number 40,887,601 and divide it by 2:
40,887,601 ÷ 2 = 20,443,800.5
If the quotient is a whole number, then 2 and 20,443,800.5 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 | 40,887,601 | |
| -1 | -40,887,601 |
Now, we try dividing 40,887,601 by 3:
40,887,601 ÷ 3 = 13,629,200.3333
If the quotient is a whole number, then 3 and 13,629,200.3333 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 | 40,887,601 | |
| -1 | -40,887,601 |
Let's try dividing by 4:
40,887,601 ÷ 4 = 10,221,900.25
If the quotient is a whole number, then 4 and 10,221,900.25 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 | 40,887,601 | |
| -1 | 40,887,601 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 103 | 323 | 1,229 | 1,751 | 1,957 | 20,893 | 23,351 | 33,269 | 126,587 | 396,967 | 2,151,979 | 2,405,153 | 40,887,601 |
| -1 | -17 | -19 | -103 | -323 | -1,229 | -1,751 | -1,957 | -20,893 | -23,351 | -33,269 | -126,587 | -396,967 | -2,151,979 | -2,405,153 | -40,887,601 |
