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 557,748,061, 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 | 557,748,061 | |
| -1 | -557,748,061 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 557,748,061.
Example:
1 x 557,748,061 = 557,748,061
and
-1 x -557,748,061 = 557,748,061
Notice both answers equal 557,748,061
With that explanation out of the way, let's continue. Next, we take the number 557,748,061 and divide it by 2:
557,748,061 ÷ 2 = 278,874,030.5
If the quotient is a whole number, then 2 and 278,874,030.5 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 | 557,748,061 | |
| -1 | -557,748,061 |
Now, we try dividing 557,748,061 by 3:
557,748,061 ÷ 3 = 185,916,020.3333
If the quotient is a whole number, then 3 and 185,916,020.3333 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 | 557,748,061 | |
| -1 | -557,748,061 |
Let's try dividing by 4:
557,748,061 ÷ 4 = 139,437,015.25
If the quotient is a whole number, then 4 and 139,437,015.25 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 | 557,748,061 | |
| -1 | 557,748,061 |
If you did it right, you will end up with this table:
| 1 | 13 | 181 | 293 | 809 | 2,353 | 3,809 | 10,517 | 53,033 | 146,429 | 237,037 | 689,429 | 1,903,577 | 3,081,481 | 42,903,697 | 557,748,061 |
| -1 | -13 | -181 | -293 | -809 | -2,353 | -3,809 | -10,517 | -53,033 | -146,429 | -237,037 | -689,429 | -1,903,577 | -3,081,481 | -42,903,697 | -557,748,061 |
