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 657,723,353, 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 | 657,723,353 | |
| -1 | -657,723,353 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 657,723,353.
Example:
1 x 657,723,353 = 657,723,353
and
-1 x -657,723,353 = 657,723,353
Notice both answers equal 657,723,353
With that explanation out of the way, let's continue. Next, we take the number 657,723,353 and divide it by 2:
657,723,353 ÷ 2 = 328,861,676.5
If the quotient is a whole number, then 2 and 328,861,676.5 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 | 657,723,353 | |
| -1 | -657,723,353 |
Now, we try dividing 657,723,353 by 3:
657,723,353 ÷ 3 = 219,241,117.6667
If the quotient is a whole number, then 3 and 219,241,117.6667 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 | 657,723,353 | |
| -1 | -657,723,353 |
Let's try dividing by 4:
657,723,353 ÷ 4 = 164,430,838.25
If the quotient is a whole number, then 4 and 164,430,838.25 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 | 657,723,353 | |
| -1 | 657,723,353 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 41 | 119 | 287 | 697 | 4,879 | 134,807 | 943,649 | 2,291,719 | 5,527,087 | 16,042,033 | 38,689,609 | 93,960,479 | 657,723,353 |
| -1 | -7 | -17 | -41 | -119 | -287 | -697 | -4,879 | -134,807 | -943,649 | -2,291,719 | -5,527,087 | -16,042,033 | -38,689,609 | -93,960,479 | -657,723,353 |
