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 378,250,801, 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 | 378,250,801 | |
| -1 | -378,250,801 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 378,250,801.
Example:
1 x 378,250,801 = 378,250,801
and
-1 x -378,250,801 = 378,250,801
Notice both answers equal 378,250,801
With that explanation out of the way, let's continue. Next, we take the number 378,250,801 and divide it by 2:
378,250,801 ÷ 2 = 189,125,400.5
If the quotient is a whole number, then 2 and 189,125,400.5 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 | 378,250,801 | |
| -1 | -378,250,801 |
Now, we try dividing 378,250,801 by 3:
378,250,801 ÷ 3 = 126,083,600.3333
If the quotient is a whole number, then 3 and 126,083,600.3333 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 | 378,250,801 | |
| -1 | -378,250,801 |
Let's try dividing by 4:
378,250,801 ÷ 4 = 94,562,700.25
If the quotient is a whole number, then 4 and 94,562,700.25 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 | 378,250,801 | |
| -1 | 378,250,801 |
If you did it right, you will end up with this table:
| 1 | 23 | 89 | 257 | 719 | 2,047 | 5,911 | 16,537 | 22,873 | 63,991 | 184,783 | 526,079 | 1,471,793 | 4,250,009 | 16,445,687 | 378,250,801 |
| -1 | -23 | -89 | -257 | -719 | -2,047 | -5,911 | -16,537 | -22,873 | -63,991 | -184,783 | -526,079 | -1,471,793 | -4,250,009 | -16,445,687 | -378,250,801 |
