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 257,763,737, 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 | 257,763,737 | |
| -1 | -257,763,737 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 257,763,737.
Example:
1 x 257,763,737 = 257,763,737
and
-1 x -257,763,737 = 257,763,737
Notice both answers equal 257,763,737
With that explanation out of the way, let's continue. Next, we take the number 257,763,737 and divide it by 2:
257,763,737 ÷ 2 = 128,881,868.5
If the quotient is a whole number, then 2 and 128,881,868.5 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 | 257,763,737 | |
| -1 | -257,763,737 |
Now, we try dividing 257,763,737 by 3:
257,763,737 ÷ 3 = 85,921,245.6667
If the quotient is a whole number, then 3 and 85,921,245.6667 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 | 257,763,737 | |
| -1 | -257,763,737 |
Let's try dividing by 4:
257,763,737 ÷ 4 = 64,440,934.25
If the quotient is a whole number, then 4 and 64,440,934.25 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 | 257,763,737 | |
| -1 | 257,763,737 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 77 | 161 | 253 | 1,771 | 145,547 | 1,018,829 | 1,601,017 | 3,347,581 | 11,207,119 | 23,433,067 | 36,823,391 | 257,763,737 |
| -1 | -7 | -11 | -23 | -77 | -161 | -253 | -1,771 | -145,547 | -1,018,829 | -1,601,017 | -3,347,581 | -11,207,119 | -23,433,067 | -36,823,391 | -257,763,737 |
