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 43,134,203, 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 | 43,134,203 | |
| -1 | -43,134,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,134,203.
Example:
1 x 43,134,203 = 43,134,203
and
-1 x -43,134,203 = 43,134,203
Notice both answers equal 43,134,203
With that explanation out of the way, let's continue. Next, we take the number 43,134,203 and divide it by 2:
43,134,203 ÷ 2 = 21,567,101.5
If the quotient is a whole number, then 2 and 21,567,101.5 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 | 43,134,203 | |
| -1 | -43,134,203 |
Now, we try dividing 43,134,203 by 3:
43,134,203 ÷ 3 = 14,378,067.6667
If the quotient is a whole number, then 3 and 14,378,067.6667 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 | 43,134,203 | |
| -1 | -43,134,203 |
Let's try dividing by 4:
43,134,203 ÷ 4 = 10,783,550.75
If the quotient is a whole number, then 4 and 10,783,550.75 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 | 43,134,203 | |
| -1 | 43,134,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 47 | 301 | 329 | 2,021 | 3,049 | 14,147 | 21,343 | 131,107 | 143,303 | 917,749 | 1,003,121 | 6,162,029 | 43,134,203 |
| -1 | -7 | -43 | -47 | -301 | -329 | -2,021 | -3,049 | -14,147 | -21,343 | -131,107 | -143,303 | -917,749 | -1,003,121 | -6,162,029 | -43,134,203 |
