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 40,383,745, 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 | 40,383,745 | |
| -1 | -40,383,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,383,745.
Example:
1 x 40,383,745 = 40,383,745
and
-1 x -40,383,745 = 40,383,745
Notice both answers equal 40,383,745
With that explanation out of the way, let's continue. Next, we take the number 40,383,745 and divide it by 2:
40,383,745 ÷ 2 = 20,191,872.5
If the quotient is a whole number, then 2 and 20,191,872.5 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 | 40,383,745 | |
| -1 | -40,383,745 |
Now, we try dividing 40,383,745 by 3:
40,383,745 ÷ 3 = 13,461,248.3333
If the quotient is a whole number, then 3 and 13,461,248.3333 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 | 40,383,745 | |
| -1 | -40,383,745 |
Let's try dividing by 4:
40,383,745 ÷ 4 = 10,095,936.25
If the quotient is a whole number, then 4 and 10,095,936.25 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 | 40,383,745 | |
| -1 | 40,383,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 433 | 811 | 2,165 | 4,055 | 9,959 | 18,653 | 49,795 | 93,265 | 351,163 | 1,755,815 | 8,076,749 | 40,383,745 |
| -1 | -5 | -23 | -115 | -433 | -811 | -2,165 | -4,055 | -9,959 | -18,653 | -49,795 | -93,265 | -351,163 | -1,755,815 | -8,076,749 | -40,383,745 |
