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 306,306,377, 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 | 306,306,377 | |
| -1 | -306,306,377 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,306,377.
Example:
1 x 306,306,377 = 306,306,377
and
-1 x -306,306,377 = 306,306,377
Notice both answers equal 306,306,377
With that explanation out of the way, let's continue. Next, we take the number 306,306,377 and divide it by 2:
306,306,377 ÷ 2 = 153,153,188.5
If the quotient is a whole number, then 2 and 153,153,188.5 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 | 306,306,377 | |
| -1 | -306,306,377 |
Now, we try dividing 306,306,377 by 3:
306,306,377 ÷ 3 = 102,102,125.6667
If the quotient is a whole number, then 3 and 102,102,125.6667 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 | 306,306,377 | |
| -1 | -306,306,377 |
Let's try dividing by 4:
306,306,377 ÷ 4 = 76,576,594.25
If the quotient is a whole number, then 4 and 76,576,594.25 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 | 306,306,377 | |
| -1 | 306,306,377 |
If you did it right, you will end up with this table:
| 1 | 13 | 139 | 337 | 503 | 1,807 | 4,381 | 6,539 | 46,843 | 69,917 | 169,511 | 608,959 | 908,921 | 2,203,643 | 23,562,029 | 306,306,377 |
| -1 | -13 | -139 | -337 | -503 | -1,807 | -4,381 | -6,539 | -46,843 | -69,917 | -169,511 | -608,959 | -908,921 | -2,203,643 | -23,562,029 | -306,306,377 |
