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 89,555,873, 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 | 89,555,873 | |
| -1 | -89,555,873 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 89,555,873.
Example:
1 x 89,555,873 = 89,555,873
and
-1 x -89,555,873 = 89,555,873
Notice both answers equal 89,555,873
With that explanation out of the way, let's continue. Next, we take the number 89,555,873 and divide it by 2:
89,555,873 ÷ 2 = 44,777,936.5
If the quotient is a whole number, then 2 and 44,777,936.5 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 | 89,555,873 | |
| -1 | -89,555,873 |
Now, we try dividing 89,555,873 by 3:
89,555,873 ÷ 3 = 29,851,957.6667
If the quotient is a whole number, then 3 and 29,851,957.6667 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 | 89,555,873 | |
| -1 | -89,555,873 |
Let's try dividing by 4:
89,555,873 ÷ 4 = 22,388,968.25
If the quotient is a whole number, then 4 and 22,388,968.25 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 | 89,555,873 | |
| -1 | 89,555,873 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 37 | 209 | 313 | 407 | 703 | 1,369 | 3,443 | 5,947 | 7,733 | 11,581 | 15,059 | 26,011 | 65,417 | 127,391 | 220,039 | 286,121 | 428,497 | 2,420,429 | 4,713,467 | 8,141,443 | 89,555,873 |
| -1 | -11 | -19 | -37 | -209 | -313 | -407 | -703 | -1,369 | -3,443 | -5,947 | -7,733 | -11,581 | -15,059 | -26,011 | -65,417 | -127,391 | -220,039 | -286,121 | -428,497 | -2,420,429 | -4,713,467 | -8,141,443 | -89,555,873 |
