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 88,837,121, 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 | 88,837,121 | |
| -1 | -88,837,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 88,837,121.
Example:
1 x 88,837,121 = 88,837,121
and
-1 x -88,837,121 = 88,837,121
Notice both answers equal 88,837,121
With that explanation out of the way, let's continue. Next, we take the number 88,837,121 and divide it by 2:
88,837,121 ÷ 2 = 44,418,560.5
If the quotient is a whole number, then 2 and 44,418,560.5 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 | 88,837,121 | |
| -1 | -88,837,121 |
Now, we try dividing 88,837,121 by 3:
88,837,121 ÷ 3 = 29,612,373.6667
If the quotient is a whole number, then 3 and 29,612,373.6667 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 | 88,837,121 | |
| -1 | -88,837,121 |
Let's try dividing by 4:
88,837,121 ÷ 4 = 22,209,280.25
If the quotient is a whole number, then 4 and 22,209,280.25 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 | 88,837,121 | |
| -1 | 88,837,121 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 367 | 491 | 493 | 6,239 | 8,347 | 10,643 | 14,239 | 180,197 | 180,931 | 242,063 | 3,063,349 | 5,225,713 | 88,837,121 |
| -1 | -17 | -29 | -367 | -491 | -493 | -6,239 | -8,347 | -10,643 | -14,239 | -180,197 | -180,931 | -242,063 | -3,063,349 | -5,225,713 | -88,837,121 |
