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 554,566,129, 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 | 554,566,129 | |
| -1 | -554,566,129 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 554,566,129.
Example:
1 x 554,566,129 = 554,566,129
and
-1 x -554,566,129 = 554,566,129
Notice both answers equal 554,566,129
With that explanation out of the way, let's continue. Next, we take the number 554,566,129 and divide it by 2:
554,566,129 ÷ 2 = 277,283,064.5
If the quotient is a whole number, then 2 and 277,283,064.5 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 | 554,566,129 | |
| -1 | -554,566,129 |
Now, we try dividing 554,566,129 by 3:
554,566,129 ÷ 3 = 184,855,376.3333
If the quotient is a whole number, then 3 and 184,855,376.3333 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 | 554,566,129 | |
| -1 | -554,566,129 |
Let's try dividing by 4:
554,566,129 ÷ 4 = 138,641,532.25
If the quotient is a whole number, then 4 and 138,641,532.25 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 | 554,566,129 | |
| -1 | 554,566,129 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 19 | 221 | 247 | 323 | 4,199 | 132,071 | 1,716,923 | 2,245,207 | 2,509,349 | 29,187,691 | 32,621,537 | 42,658,933 | 554,566,129 |
| -1 | -13 | -17 | -19 | -221 | -247 | -323 | -4,199 | -132,071 | -1,716,923 | -2,245,207 | -2,509,349 | -29,187,691 | -32,621,537 | -42,658,933 | -554,566,129 |
