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 183,680,783, 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 | 183,680,783 | |
| -1 | -183,680,783 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 183,680,783.
Example:
1 x 183,680,783 = 183,680,783
and
-1 x -183,680,783 = 183,680,783
Notice both answers equal 183,680,783
With that explanation out of the way, let's continue. Next, we take the number 183,680,783 and divide it by 2:
183,680,783 ÷ 2 = 91,840,391.5
If the quotient is a whole number, then 2 and 91,840,391.5 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 | 183,680,783 | |
| -1 | -183,680,783 |
Now, we try dividing 183,680,783 by 3:
183,680,783 ÷ 3 = 61,226,927.6667
If the quotient is a whole number, then 3 and 61,226,927.6667 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 | 183,680,783 | |
| -1 | -183,680,783 |
Let's try dividing by 4:
183,680,783 ÷ 4 = 45,920,195.75
If the quotient is a whole number, then 4 and 45,920,195.75 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 | 183,680,783 | |
| -1 | 183,680,783 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 23 | 121 | 143 | 253 | 299 | 1,573 | 2,783 | 3,289 | 5,077 | 36,179 | 55,847 | 66,001 | 116,771 | 614,317 | 726,011 | 1,284,481 | 1,518,023 | 7,986,121 | 14,129,291 | 16,698,253 | 183,680,783 |
| -1 | -11 | -13 | -23 | -121 | -143 | -253 | -299 | -1,573 | -2,783 | -3,289 | -5,077 | -36,179 | -55,847 | -66,001 | -116,771 | -614,317 | -726,011 | -1,284,481 | -1,518,023 | -7,986,121 | -14,129,291 | -16,698,253 | -183,680,783 |
