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 554,362,399, 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 | 554,362,399 | |
| -1 | -554,362,399 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 554,362,399.
Example:
1 x 554,362,399 = 554,362,399
and
-1 x -554,362,399 = 554,362,399
Notice both answers equal 554,362,399
With that explanation out of the way, let's continue. Next, we take the number 554,362,399 and divide it by 2:
554,362,399 ÷ 2 = 277,181,199.5
If the quotient is a whole number, then 2 and 277,181,199.5 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 | 554,362,399 | |
| -1 | -554,362,399 |
Now, we try dividing 554,362,399 by 3:
554,362,399 ÷ 3 = 184,787,466.3333
If the quotient is a whole number, then 3 and 184,787,466.3333 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 | 554,362,399 | |
| -1 | -554,362,399 |
Let's try dividing by 4:
554,362,399 ÷ 4 = 138,590,599.75
If the quotient is a whole number, then 4 and 138,590,599.75 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 | 554,362,399 | |
| -1 | 554,362,399 |
If you did it right, you will end up with this table:
| 1 | 23 | 89 | 107 | 2,047 | 2,461 | 2,531 | 9,523 | 58,213 | 219,029 | 225,259 | 270,817 | 5,180,957 | 6,228,791 | 24,102,713 | 554,362,399 |
| -1 | -23 | -89 | -107 | -2,047 | -2,461 | -2,531 | -9,523 | -58,213 | -219,029 | -225,259 | -270,817 | -5,180,957 | -6,228,791 | -24,102,713 | -554,362,399 |
