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 43,161,889, 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 | 43,161,889 | |
| -1 | -43,161,889 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,161,889.
Example:
1 x 43,161,889 = 43,161,889
and
-1 x -43,161,889 = 43,161,889
Notice both answers equal 43,161,889
With that explanation out of the way, let's continue. Next, we take the number 43,161,889 and divide it by 2:
43,161,889 ÷ 2 = 21,580,944.5
If the quotient is a whole number, then 2 and 21,580,944.5 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 | 43,161,889 | |
| -1 | -43,161,889 |
Now, we try dividing 43,161,889 by 3:
43,161,889 ÷ 3 = 14,387,296.3333
If the quotient is a whole number, then 3 and 14,387,296.3333 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 | 43,161,889 | |
| -1 | -43,161,889 |
Let's try dividing by 4:
43,161,889 ÷ 4 = 10,790,472.25
If the quotient is a whole number, then 4 and 10,790,472.25 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 | 43,161,889 | |
| -1 | 43,161,889 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 41 | 899 | 1,171 | 1,189 | 1,271 | 33,959 | 36,301 | 36,859 | 48,011 | 1,052,729 | 1,392,319 | 1,488,341 | 43,161,889 |
| -1 | -29 | -31 | -41 | -899 | -1,171 | -1,189 | -1,271 | -33,959 | -36,301 | -36,859 | -48,011 | -1,052,729 | -1,392,319 | -1,488,341 | -43,161,889 |
