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 88,864,207, 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 | 88,864,207 | |
| -1 | -88,864,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 88,864,207.
Example:
1 x 88,864,207 = 88,864,207
and
-1 x -88,864,207 = 88,864,207
Notice both answers equal 88,864,207
With that explanation out of the way, let's continue. Next, we take the number 88,864,207 and divide it by 2:
88,864,207 ÷ 2 = 44,432,103.5
If the quotient is a whole number, then 2 and 44,432,103.5 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 | 88,864,207 | |
| -1 | -88,864,207 |
Now, we try dividing 88,864,207 by 3:
88,864,207 ÷ 3 = 29,621,402.3333
If the quotient is a whole number, then 3 and 29,621,402.3333 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 | 88,864,207 | |
| -1 | -88,864,207 |
Let's try dividing by 4:
88,864,207 ÷ 4 = 22,216,051.75
If the quotient is a whole number, then 4 and 22,216,051.75 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 | 88,864,207 | |
| -1 | 88,864,207 |
If you did it right, you will end up with this table:
| 1 | 29 | 59 | 167 | 311 | 1,711 | 4,843 | 9,019 | 9,853 | 18,349 | 51,937 | 285,737 | 532,121 | 1,506,173 | 3,064,283 | 88,864,207 |
| -1 | -29 | -59 | -167 | -311 | -1,711 | -4,843 | -9,019 | -9,853 | -18,349 | -51,937 | -285,737 | -532,121 | -1,506,173 | -3,064,283 | -88,864,207 |
