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 43,001,329, 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 | 43,001,329 | |
| -1 | -43,001,329 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,001,329.
Example:
1 x 43,001,329 = 43,001,329
and
-1 x -43,001,329 = 43,001,329
Notice both answers equal 43,001,329
With that explanation out of the way, let's continue. Next, we take the number 43,001,329 and divide it by 2:
43,001,329 ÷ 2 = 21,500,664.5
If the quotient is a whole number, then 2 and 21,500,664.5 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 | 43,001,329 | |
| -1 | -43,001,329 |
Now, we try dividing 43,001,329 by 3:
43,001,329 ÷ 3 = 14,333,776.3333
If the quotient is a whole number, then 3 and 14,333,776.3333 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 | 43,001,329 | |
| -1 | -43,001,329 |
Let's try dividing by 4:
43,001,329 ÷ 4 = 10,750,332.25
If the quotient is a whole number, then 4 and 10,750,332.25 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 | 43,001,329 | |
| -1 | 43,001,329 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 89 | 161 | 623 | 2,047 | 3,001 | 14,329 | 21,007 | 69,023 | 267,089 | 483,161 | 1,869,623 | 6,143,047 | 43,001,329 |
| -1 | -7 | -23 | -89 | -161 | -623 | -2,047 | -3,001 | -14,329 | -21,007 | -69,023 | -267,089 | -483,161 | -1,869,623 | -6,143,047 | -43,001,329 |
