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 554,352,431, 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 | 554,352,431 | |
| -1 | -554,352,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 554,352,431.
Example:
1 x 554,352,431 = 554,352,431
and
-1 x -554,352,431 = 554,352,431
Notice both answers equal 554,352,431
With that explanation out of the way, let's continue. Next, we take the number 554,352,431 and divide it by 2:
554,352,431 ÷ 2 = 277,176,215.5
If the quotient is a whole number, then 2 and 277,176,215.5 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 | 554,352,431 | |
| -1 | -554,352,431 |
Now, we try dividing 554,352,431 by 3:
554,352,431 ÷ 3 = 184,784,143.6667
If the quotient is a whole number, then 3 and 184,784,143.6667 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 | 554,352,431 | |
| -1 | -554,352,431 |
Let's try dividing by 4:
554,352,431 ÷ 4 = 138,588,107.75
If the quotient is a whole number, then 4 and 138,588,107.75 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 | 554,352,431 | |
| -1 | 554,352,431 |
If you did it right, you will end up with this table:
| 1 | 41 | 43 | 89 | 1,763 | 3,533 | 3,649 | 3,827 | 144,853 | 151,919 | 156,907 | 314,437 | 6,228,679 | 12,891,917 | 13,520,791 | 554,352,431 |
| -1 | -41 | -43 | -89 | -1,763 | -3,533 | -3,649 | -3,827 | -144,853 | -151,919 | -156,907 | -314,437 | -6,228,679 | -12,891,917 | -13,520,791 | -554,352,431 |
