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 403,723,355, 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 | 403,723,355 | |
| -1 | -403,723,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,723,355.
Example:
1 x 403,723,355 = 403,723,355
and
-1 x -403,723,355 = 403,723,355
Notice both answers equal 403,723,355
With that explanation out of the way, let's continue. Next, we take the number 403,723,355 and divide it by 2:
403,723,355 ÷ 2 = 201,861,677.5
If the quotient is a whole number, then 2 and 201,861,677.5 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 | 403,723,355 | |
| -1 | -403,723,355 |
Now, we try dividing 403,723,355 by 3:
403,723,355 ÷ 3 = 134,574,451.6667
If the quotient is a whole number, then 3 and 134,574,451.6667 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 | 403,723,355 | |
| -1 | -403,723,355 |
Let's try dividing by 4:
403,723,355 ÷ 4 = 100,930,838.75
If the quotient is a whole number, then 4 and 100,930,838.75 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 | 403,723,355 | |
| -1 | 403,723,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 397,757 | 1,988,785 | 2,784,299 | 11,534,953 | 13,921,495 | 57,674,765 | 80,744,671 | 403,723,355 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -397,757 | -1,988,785 | -2,784,299 | -11,534,953 | -13,921,495 | -57,674,765 | -80,744,671 | -403,723,355 |
