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 43,421,399, 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 | 43,421,399 | |
| -1 | -43,421,399 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,421,399.
Example:
1 x 43,421,399 = 43,421,399
and
-1 x -43,421,399 = 43,421,399
Notice both answers equal 43,421,399
With that explanation out of the way, let's continue. Next, we take the number 43,421,399 and divide it by 2:
43,421,399 ÷ 2 = 21,710,699.5
If the quotient is a whole number, then 2 and 21,710,699.5 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 | 43,421,399 | |
| -1 | -43,421,399 |
Now, we try dividing 43,421,399 by 3:
43,421,399 ÷ 3 = 14,473,799.6667
If the quotient is a whole number, then 3 and 14,473,799.6667 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 | 43,421,399 | |
| -1 | -43,421,399 |
Let's try dividing by 4:
43,421,399 ÷ 4 = 10,855,349.75
If the quotient is a whole number, then 4 and 10,855,349.75 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 | 43,421,399 | |
| -1 | 43,421,399 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 71 | 343 | 497 | 1,783 | 3,479 | 12,481 | 24,353 | 87,367 | 126,593 | 611,569 | 886,151 | 6,203,057 | 43,421,399 |
| -1 | -7 | -49 | -71 | -343 | -497 | -1,783 | -3,479 | -12,481 | -24,353 | -87,367 | -126,593 | -611,569 | -886,151 | -6,203,057 | -43,421,399 |
