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 306,402,415, 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 | 306,402,415 | |
| -1 | -306,402,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,402,415.
Example:
1 x 306,402,415 = 306,402,415
and
-1 x -306,402,415 = 306,402,415
Notice both answers equal 306,402,415
With that explanation out of the way, let's continue. Next, we take the number 306,402,415 and divide it by 2:
306,402,415 ÷ 2 = 153,201,207.5
If the quotient is a whole number, then 2 and 153,201,207.5 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 | 306,402,415 | |
| -1 | -306,402,415 |
Now, we try dividing 306,402,415 by 3:
306,402,415 ÷ 3 = 102,134,138.3333
If the quotient is a whole number, then 3 and 102,134,138.3333 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 | 306,402,415 | |
| -1 | -306,402,415 |
Let's try dividing by 4:
306,402,415 ÷ 4 = 76,600,603.75
If the quotient is a whole number, then 4 and 76,600,603.75 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 | 306,402,415 | |
| -1 | 306,402,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 167 | 835 | 1,837 | 9,185 | 33,359 | 166,795 | 366,949 | 1,834,745 | 5,570,953 | 27,854,765 | 61,280,483 | 306,402,415 |
| -1 | -5 | -11 | -55 | -167 | -835 | -1,837 | -9,185 | -33,359 | -166,795 | -366,949 | -1,834,745 | -5,570,953 | -27,854,765 | -61,280,483 | -306,402,415 |
