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 554,150,339, 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 | 554,150,339 | |
| -1 | -554,150,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 554,150,339.
Example:
1 x 554,150,339 = 554,150,339
and
-1 x -554,150,339 = 554,150,339
Notice both answers equal 554,150,339
With that explanation out of the way, let's continue. Next, we take the number 554,150,339 and divide it by 2:
554,150,339 ÷ 2 = 277,075,169.5
If the quotient is a whole number, then 2 and 277,075,169.5 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 | 554,150,339 | |
| -1 | -554,150,339 |
Now, we try dividing 554,150,339 by 3:
554,150,339 ÷ 3 = 184,716,779.6667
If the quotient is a whole number, then 3 and 184,716,779.6667 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 | 554,150,339 | |
| -1 | -554,150,339 |
Let's try dividing by 4:
554,150,339 ÷ 4 = 138,537,584.75
If the quotient is a whole number, then 4 and 138,537,584.75 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 | 554,150,339 | |
| -1 | 554,150,339 |
If you did it right, you will end up with this table:
| 1 | 23 | 241 | 257 | 389 | 5,543 | 5,911 | 8,947 | 61,937 | 93,749 | 99,973 | 1,424,551 | 2,156,227 | 2,299,379 | 24,093,493 | 554,150,339 |
| -1 | -23 | -241 | -257 | -389 | -5,543 | -5,911 | -8,947 | -61,937 | -93,749 | -99,973 | -1,424,551 | -2,156,227 | -2,299,379 | -24,093,493 | -554,150,339 |
