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 43,876,133, 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 | 43,876,133 | |
| -1 | -43,876,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,876,133.
Example:
1 x 43,876,133 = 43,876,133
and
-1 x -43,876,133 = 43,876,133
Notice both answers equal 43,876,133
With that explanation out of the way, let's continue. Next, we take the number 43,876,133 and divide it by 2:
43,876,133 ÷ 2 = 21,938,066.5
If the quotient is a whole number, then 2 and 21,938,066.5 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 | 43,876,133 | |
| -1 | -43,876,133 |
Now, we try dividing 43,876,133 by 3:
43,876,133 ÷ 3 = 14,625,377.6667
If the quotient is a whole number, then 3 and 14,625,377.6667 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 | 43,876,133 | |
| -1 | -43,876,133 |
Let's try dividing by 4:
43,876,133 ÷ 4 = 10,969,033.25
If the quotient is a whole number, then 4 and 10,969,033.25 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 | 43,876,133 | |
| -1 | 43,876,133 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 307 | 1,201 | 2,149 | 5,219 | 8,407 | 20,417 | 36,533 | 142,919 | 368,707 | 2,580,949 | 6,268,019 | 43,876,133 |
| -1 | -7 | -17 | -119 | -307 | -1,201 | -2,149 | -5,219 | -8,407 | -20,417 | -36,533 | -142,919 | -368,707 | -2,580,949 | -6,268,019 | -43,876,133 |
