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 43,321,043, 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 | 43,321,043 | |
| -1 | -43,321,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,321,043.
Example:
1 x 43,321,043 = 43,321,043
and
-1 x -43,321,043 = 43,321,043
Notice both answers equal 43,321,043
With that explanation out of the way, let's continue. Next, we take the number 43,321,043 and divide it by 2:
43,321,043 ÷ 2 = 21,660,521.5
If the quotient is a whole number, then 2 and 21,660,521.5 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 | 43,321,043 | |
| -1 | -43,321,043 |
Now, we try dividing 43,321,043 by 3:
43,321,043 ÷ 3 = 14,440,347.6667
If the quotient is a whole number, then 3 and 14,440,347.6667 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 | 43,321,043 | |
| -1 | -43,321,043 |
Let's try dividing by 4:
43,321,043 ÷ 4 = 10,830,260.75
If the quotient is a whole number, then 4 and 10,830,260.75 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 | 43,321,043 | |
| -1 | 43,321,043 |
If you did it right, you will end up with this table:
| 1 | 31 | 37 | 179 | 211 | 1,147 | 5,549 | 6,541 | 6,623 | 7,807 | 37,769 | 205,313 | 242,017 | 1,170,839 | 1,397,453 | 43,321,043 |
| -1 | -31 | -37 | -179 | -211 | -1,147 | -5,549 | -6,541 | -6,623 | -7,807 | -37,769 | -205,313 | -242,017 | -1,170,839 | -1,397,453 | -43,321,043 |
