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 403,041,443, 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 | 403,041,443 | |
| -1 | -403,041,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,041,443.
Example:
1 x 403,041,443 = 403,041,443
and
-1 x -403,041,443 = 403,041,443
Notice both answers equal 403,041,443
With that explanation out of the way, let's continue. Next, we take the number 403,041,443 and divide it by 2:
403,041,443 ÷ 2 = 201,520,721.5
If the quotient is a whole number, then 2 and 201,520,721.5 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 | 403,041,443 | |
| -1 | -403,041,443 |
Now, we try dividing 403,041,443 by 3:
403,041,443 ÷ 3 = 134,347,147.6667
If the quotient is a whole number, then 3 and 134,347,147.6667 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 | 403,041,443 | |
| -1 | -403,041,443 |
Let's try dividing by 4:
403,041,443 ÷ 4 = 100,760,360.75
If the quotient is a whole number, then 4 and 100,760,360.75 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 | 403,041,443 | |
| -1 | 403,041,443 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 83 | 161 | 581 | 1,909 | 13,363 | 30,161 | 211,127 | 693,703 | 2,503,363 | 4,855,921 | 17,523,541 | 57,577,349 | 403,041,443 |
| -1 | -7 | -23 | -83 | -161 | -581 | -1,909 | -13,363 | -30,161 | -211,127 | -693,703 | -2,503,363 | -4,855,921 | -17,523,541 | -57,577,349 | -403,041,443 |
