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 431,463,545, 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 | 431,463,545 | |
| -1 | -431,463,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 431,463,545.
Example:
1 x 431,463,545 = 431,463,545
and
-1 x -431,463,545 = 431,463,545
Notice both answers equal 431,463,545
With that explanation out of the way, let's continue. Next, we take the number 431,463,545 and divide it by 2:
431,463,545 ÷ 2 = 215,731,772.5
If the quotient is a whole number, then 2 and 215,731,772.5 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 | 431,463,545 | |
| -1 | -431,463,545 |
Now, we try dividing 431,463,545 by 3:
431,463,545 ÷ 3 = 143,821,181.6667
If the quotient is a whole number, then 3 and 143,821,181.6667 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 | 431,463,545 | |
| -1 | -431,463,545 |
Let's try dividing by 4:
431,463,545 ÷ 4 = 107,865,886.25
If the quotient is a whole number, then 4 and 107,865,886.25 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 | 431,463,545 | |
| -1 | 431,463,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 445 | 521 | 1,861 | 2,605 | 9,305 | 46,369 | 165,629 | 231,845 | 828,145 | 969,581 | 4,847,905 | 86,292,709 | 431,463,545 |
| -1 | -5 | -89 | -445 | -521 | -1,861 | -2,605 | -9,305 | -46,369 | -165,629 | -231,845 | -828,145 | -969,581 | -4,847,905 | -86,292,709 | -431,463,545 |
