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 306,375,275, 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 | 306,375,275 | |
| -1 | -306,375,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,375,275.
Example:
1 x 306,375,275 = 306,375,275
and
-1 x -306,375,275 = 306,375,275
Notice both answers equal 306,375,275
With that explanation out of the way, let's continue. Next, we take the number 306,375,275 and divide it by 2:
306,375,275 ÷ 2 = 153,187,637.5
If the quotient is a whole number, then 2 and 153,187,637.5 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 | 306,375,275 | |
| -1 | -306,375,275 |
Now, we try dividing 306,375,275 by 3:
306,375,275 ÷ 3 = 102,125,091.6667
If the quotient is a whole number, then 3 and 102,125,091.6667 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 | 306,375,275 | |
| -1 | -306,375,275 |
Let's try dividing by 4:
306,375,275 ÷ 4 = 76,593,818.75
If the quotient is a whole number, then 4 and 76,593,818.75 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 | 306,375,275 | |
| -1 | 306,375,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 263 | 425 | 1,315 | 2,741 | 4,471 | 6,575 | 13,705 | 22,355 | 46,597 | 68,525 | 111,775 | 232,985 | 720,883 | 1,164,925 | 3,604,415 | 12,255,011 | 18,022,075 | 61,275,055 | 306,375,275 |
| -1 | -5 | -17 | -25 | -85 | -263 | -425 | -1,315 | -2,741 | -4,471 | -6,575 | -13,705 | -22,355 | -46,597 | -68,525 | -111,775 | -232,985 | -720,883 | -1,164,925 | -3,604,415 | -12,255,011 | -18,022,075 | -61,275,055 | -306,375,275 |
