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 183,765,127, 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 | 183,765,127 | |
| -1 | -183,765,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 183,765,127.
Example:
1 x 183,765,127 = 183,765,127
and
-1 x -183,765,127 = 183,765,127
Notice both answers equal 183,765,127
With that explanation out of the way, let's continue. Next, we take the number 183,765,127 and divide it by 2:
183,765,127 ÷ 2 = 91,882,563.5
If the quotient is a whole number, then 2 and 91,882,563.5 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 | 183,765,127 | |
| -1 | -183,765,127 |
Now, we try dividing 183,765,127 by 3:
183,765,127 ÷ 3 = 61,255,042.3333
If the quotient is a whole number, then 3 and 61,255,042.3333 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 | 183,765,127 | |
| -1 | -183,765,127 |
Let's try dividing by 4:
183,765,127 ÷ 4 = 45,941,281.75
If the quotient is a whole number, then 4 and 45,941,281.75 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 | 183,765,127 | |
| -1 | 183,765,127 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 149 | 1,043 | 1,937 | 13,553 | 13,559 | 94,871 | 176,189 | 1,233,323 | 2,019,397 | 14,135,779 | 26,252,161 | 183,765,127 |
| -1 | -7 | -13 | -91 | -149 | -1,043 | -1,937 | -13,553 | -13,559 | -94,871 | -176,189 | -1,233,323 | -2,019,397 | -14,135,779 | -26,252,161 | -183,765,127 |
