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 431,054,437, 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 | 431,054,437 | |
| -1 | -431,054,437 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 431,054,437.
Example:
1 x 431,054,437 = 431,054,437
and
-1 x -431,054,437 = 431,054,437
Notice both answers equal 431,054,437
With that explanation out of the way, let's continue. Next, we take the number 431,054,437 and divide it by 2:
431,054,437 ÷ 2 = 215,527,218.5
If the quotient is a whole number, then 2 and 215,527,218.5 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 | 431,054,437 | |
| -1 | -431,054,437 |
Now, we try dividing 431,054,437 by 3:
431,054,437 ÷ 3 = 143,684,812.3333
If the quotient is a whole number, then 3 and 143,684,812.3333 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 | 431,054,437 | |
| -1 | -431,054,437 |
Let's try dividing by 4:
431,054,437 ÷ 4 = 107,763,609.25
If the quotient is a whole number, then 4 and 107,763,609.25 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 | 431,054,437 | |
| -1 | 431,054,437 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 349 | 517 | 2,389 | 3,839 | 16,403 | 26,279 | 112,283 | 180,433 | 833,761 | 1,235,113 | 9,171,371 | 39,186,767 | 431,054,437 |
| -1 | -11 | -47 | -349 | -517 | -2,389 | -3,839 | -16,403 | -26,279 | -112,283 | -180,433 | -833,761 | -1,235,113 | -9,171,371 | -39,186,767 | -431,054,437 |
