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 305,476,775, 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 | 305,476,775 | |
| -1 | -305,476,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 305,476,775.
Example:
1 x 305,476,775 = 305,476,775
and
-1 x -305,476,775 = 305,476,775
Notice both answers equal 305,476,775
With that explanation out of the way, let's continue. Next, we take the number 305,476,775 and divide it by 2:
305,476,775 ÷ 2 = 152,738,387.5
If the quotient is a whole number, then 2 and 152,738,387.5 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 | 305,476,775 | |
| -1 | -305,476,775 |
Now, we try dividing 305,476,775 by 3:
305,476,775 ÷ 3 = 101,825,591.6667
If the quotient is a whole number, then 3 and 101,825,591.6667 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 | 305,476,775 | |
| -1 | -305,476,775 |
Let's try dividing by 4:
305,476,775 ÷ 4 = 76,369,193.75
If the quotient is a whole number, then 4 and 76,369,193.75 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 | 305,476,775 | |
| -1 | 305,476,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 151 | 475 | 755 | 2,869 | 3,775 | 4,259 | 14,345 | 21,295 | 71,725 | 80,921 | 106,475 | 404,605 | 643,109 | 2,023,025 | 3,215,545 | 12,219,071 | 16,077,725 | 61,095,355 | 305,476,775 |
| -1 | -5 | -19 | -25 | -95 | -151 | -475 | -755 | -2,869 | -3,775 | -4,259 | -14,345 | -21,295 | -71,725 | -80,921 | -106,475 | -404,605 | -643,109 | -2,023,025 | -3,215,545 | -12,219,071 | -16,077,725 | -61,095,355 | -305,476,775 |
