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 306,377,315, 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 | 306,377,315 | |
| -1 | -306,377,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,377,315.
Example:
1 x 306,377,315 = 306,377,315
and
-1 x -306,377,315 = 306,377,315
Notice both answers equal 306,377,315
With that explanation out of the way, let's continue. Next, we take the number 306,377,315 and divide it by 2:
306,377,315 ÷ 2 = 153,188,657.5
If the quotient is a whole number, then 2 and 153,188,657.5 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 | 306,377,315 | |
| -1 | -306,377,315 |
Now, we try dividing 306,377,315 by 3:
306,377,315 ÷ 3 = 102,125,771.6667
If the quotient is a whole number, then 3 and 102,125,771.6667 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 | 306,377,315 | |
| -1 | -306,377,315 |
Let's try dividing by 4:
306,377,315 ÷ 4 = 76,594,328.75
If the quotient is a whole number, then 4 and 76,594,328.75 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 | 306,377,315 | |
| -1 | 306,377,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 29 | 85 | 145 | 493 | 2,465 | 124,291 | 621,455 | 2,112,947 | 3,604,439 | 10,564,735 | 18,022,195 | 61,275,463 | 306,377,315 |
| -1 | -5 | -17 | -29 | -85 | -145 | -493 | -2,465 | -124,291 | -621,455 | -2,112,947 | -3,604,439 | -10,564,735 | -18,022,195 | -61,275,463 | -306,377,315 |
