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 576,637,139, 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 | 576,637,139 | |
| -1 | -576,637,139 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 576,637,139.
Example:
1 x 576,637,139 = 576,637,139
and
-1 x -576,637,139 = 576,637,139
Notice both answers equal 576,637,139
With that explanation out of the way, let's continue. Next, we take the number 576,637,139 and divide it by 2:
576,637,139 ÷ 2 = 288,318,569.5
If the quotient is a whole number, then 2 and 288,318,569.5 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 | 576,637,139 | |
| -1 | -576,637,139 |
Now, we try dividing 576,637,139 by 3:
576,637,139 ÷ 3 = 192,212,379.6667
If the quotient is a whole number, then 3 and 192,212,379.6667 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 | 576,637,139 | |
| -1 | -576,637,139 |
Let's try dividing by 4:
576,637,139 ÷ 4 = 144,159,284.75
If the quotient is a whole number, then 4 and 144,159,284.75 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 | 576,637,139 | |
| -1 | 576,637,139 |
If you did it right, you will end up with this table:
| 1 | 13 | 151 | 167 | 1,759 | 1,963 | 2,171 | 22,867 | 25,217 | 265,609 | 293,753 | 327,821 | 3,452,917 | 3,818,789 | 44,356,703 | 576,637,139 |
| -1 | -13 | -151 | -167 | -1,759 | -1,963 | -2,171 | -22,867 | -25,217 | -265,609 | -293,753 | -327,821 | -3,452,917 | -3,818,789 | -44,356,703 | -576,637,139 |
