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 321,133,025, 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 | 321,133,025 | |
| -1 | -321,133,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,133,025.
Example:
1 x 321,133,025 = 321,133,025
and
-1 x -321,133,025 = 321,133,025
Notice both answers equal 321,133,025
With that explanation out of the way, let's continue. Next, we take the number 321,133,025 and divide it by 2:
321,133,025 ÷ 2 = 160,566,512.5
If the quotient is a whole number, then 2 and 160,566,512.5 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 | 321,133,025 | |
| -1 | -321,133,025 |
Now, we try dividing 321,133,025 by 3:
321,133,025 ÷ 3 = 107,044,341.6667
If the quotient is a whole number, then 3 and 107,044,341.6667 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 | 321,133,025 | |
| -1 | -321,133,025 |
Let's try dividing by 4:
321,133,025 ÷ 4 = 80,283,256.25
If the quotient is a whole number, then 4 and 80,283,256.25 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 | 321,133,025 | |
| -1 | 321,133,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 79 | 277 | 395 | 587 | 1,385 | 1,975 | 2,935 | 6,925 | 14,675 | 21,883 | 46,373 | 109,415 | 162,599 | 231,865 | 547,075 | 812,995 | 1,159,325 | 4,064,975 | 12,845,321 | 64,226,605 | 321,133,025 |
| -1 | -5 | -25 | -79 | -277 | -395 | -587 | -1,385 | -1,975 | -2,935 | -6,925 | -14,675 | -21,883 | -46,373 | -109,415 | -162,599 | -231,865 | -547,075 | -812,995 | -1,159,325 | -4,064,975 | -12,845,321 | -64,226,605 | -321,133,025 |
