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 87,433,511, 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 | 87,433,511 | |
| -1 | -87,433,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 87,433,511.
Example:
1 x 87,433,511 = 87,433,511
and
-1 x -87,433,511 = 87,433,511
Notice both answers equal 87,433,511
With that explanation out of the way, let's continue. Next, we take the number 87,433,511 and divide it by 2:
87,433,511 ÷ 2 = 43,716,755.5
If the quotient is a whole number, then 2 and 43,716,755.5 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 | 87,433,511 | |
| -1 | -87,433,511 |
Now, we try dividing 87,433,511 by 3:
87,433,511 ÷ 3 = 29,144,503.6667
If the quotient is a whole number, then 3 and 29,144,503.6667 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 | 87,433,511 | |
| -1 | -87,433,511 |
Let's try dividing by 4:
87,433,511 ÷ 4 = 21,858,377.75
If the quotient is a whole number, then 4 and 21,858,377.75 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 | 87,433,511 | |
| -1 | 87,433,511 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 89 | 121 | 253 | 353 | 979 | 2,047 | 2,783 | 3,883 | 8,119 | 10,769 | 22,517 | 31,417 | 42,713 | 89,309 | 247,687 | 345,587 | 722,591 | 982,399 | 3,801,457 | 7,948,501 | 87,433,511 |
| -1 | -11 | -23 | -89 | -121 | -253 | -353 | -979 | -2,047 | -2,783 | -3,883 | -8,119 | -10,769 | -22,517 | -31,417 | -42,713 | -89,309 | -247,687 | -345,587 | -722,591 | -982,399 | -3,801,457 | -7,948,501 | -87,433,511 |
