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 43,001,203, 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 | 43,001,203 | |
| -1 | -43,001,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,001,203.
Example:
1 x 43,001,203 = 43,001,203
and
-1 x -43,001,203 = 43,001,203
Notice both answers equal 43,001,203
With that explanation out of the way, let's continue. Next, we take the number 43,001,203 and divide it by 2:
43,001,203 ÷ 2 = 21,500,601.5
If the quotient is a whole number, then 2 and 21,500,601.5 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 | 43,001,203 | |
| -1 | -43,001,203 |
Now, we try dividing 43,001,203 by 3:
43,001,203 ÷ 3 = 14,333,734.3333
If the quotient is a whole number, then 3 and 14,333,734.3333 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 | 43,001,203 | |
| -1 | -43,001,203 |
Let's try dividing by 4:
43,001,203 ÷ 4 = 10,750,300.75
If the quotient is a whole number, then 4 and 10,750,300.75 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 | 43,001,203 | |
| -1 | 43,001,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 277 | 331 | 469 | 1,939 | 2,317 | 18,559 | 22,177 | 91,687 | 129,913 | 155,239 | 641,809 | 6,143,029 | 43,001,203 |
| -1 | -7 | -67 | -277 | -331 | -469 | -1,939 | -2,317 | -18,559 | -22,177 | -91,687 | -129,913 | -155,239 | -641,809 | -6,143,029 | -43,001,203 |
