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 321,654,061, 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 | 321,654,061 | |
| -1 | -321,654,061 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,654,061.
Example:
1 x 321,654,061 = 321,654,061
and
-1 x -321,654,061 = 321,654,061
Notice both answers equal 321,654,061
With that explanation out of the way, let's continue. Next, we take the number 321,654,061 and divide it by 2:
321,654,061 ÷ 2 = 160,827,030.5
If the quotient is a whole number, then 2 and 160,827,030.5 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 | 321,654,061 | |
| -1 | -321,654,061 |
Now, we try dividing 321,654,061 by 3:
321,654,061 ÷ 3 = 107,218,020.3333
If the quotient is a whole number, then 3 and 107,218,020.3333 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 | 321,654,061 | |
| -1 | -321,654,061 |
Let's try dividing by 4:
321,654,061 ÷ 4 = 80,413,515.25
If the quotient is a whole number, then 4 and 80,413,515.25 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 | 321,654,061 | |
| -1 | 321,654,061 |
If you did it right, you will end up with this table:
| 1 | 37 | 41 | 43 | 1,517 | 1,591 | 1,763 | 4,931 | 65,231 | 182,447 | 202,171 | 212,033 | 7,480,327 | 7,845,221 | 8,693,353 | 321,654,061 |
| -1 | -37 | -41 | -43 | -1,517 | -1,591 | -1,763 | -4,931 | -65,231 | -182,447 | -202,171 | -212,033 | -7,480,327 | -7,845,221 | -8,693,353 | -321,654,061 |
