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 43,001,387, 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 | 43,001,387 | |
| -1 | -43,001,387 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,001,387.
Example:
1 x 43,001,387 = 43,001,387
and
-1 x -43,001,387 = 43,001,387
Notice both answers equal 43,001,387
With that explanation out of the way, let's continue. Next, we take the number 43,001,387 and divide it by 2:
43,001,387 ÷ 2 = 21,500,693.5
If the quotient is a whole number, then 2 and 21,500,693.5 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 | 43,001,387 | |
| -1 | -43,001,387 |
Now, we try dividing 43,001,387 by 3:
43,001,387 ÷ 3 = 14,333,795.6667
If the quotient is a whole number, then 3 and 14,333,795.6667 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 | 43,001,387 | |
| -1 | -43,001,387 |
Let's try dividing by 4:
43,001,387 ÷ 4 = 10,750,346.75
If the quotient is a whole number, then 4 and 10,750,346.75 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 | 43,001,387 | |
| -1 | 43,001,387 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 83 | 143 | 913 | 1,079 | 3,623 | 11,869 | 39,853 | 47,099 | 300,709 | 518,089 | 3,307,799 | 3,909,217 | 43,001,387 |
| -1 | -11 | -13 | -83 | -143 | -913 | -1,079 | -3,623 | -11,869 | -39,853 | -47,099 | -300,709 | -518,089 | -3,307,799 | -3,909,217 | -43,001,387 |
