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 102,502,855, 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 | 102,502,855 | |
| -1 | -102,502,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,502,855.
Example:
1 x 102,502,855 = 102,502,855
and
-1 x -102,502,855 = 102,502,855
Notice both answers equal 102,502,855
With that explanation out of the way, let's continue. Next, we take the number 102,502,855 and divide it by 2:
102,502,855 ÷ 2 = 51,251,427.5
If the quotient is a whole number, then 2 and 51,251,427.5 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 | 102,502,855 | |
| -1 | -102,502,855 |
Now, we try dividing 102,502,855 by 3:
102,502,855 ÷ 3 = 34,167,618.3333
If the quotient is a whole number, then 3 and 34,167,618.3333 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 | 102,502,855 | |
| -1 | -102,502,855 |
Let's try dividing by 4:
102,502,855 ÷ 4 = 25,625,713.75
If the quotient is a whole number, then 4 and 25,625,713.75 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 | 102,502,855 | |
| -1 | 102,502,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 49 | 65 | 91 | 245 | 455 | 637 | 3,185 | 32,183 | 160,915 | 225,281 | 418,379 | 1,126,405 | 1,576,967 | 2,091,895 | 2,928,653 | 7,884,835 | 14,643,265 | 20,500,571 | 102,502,855 |
| -1 | -5 | -7 | -13 | -35 | -49 | -65 | -91 | -245 | -455 | -637 | -3,185 | -32,183 | -160,915 | -225,281 | -418,379 | -1,126,405 | -1,576,967 | -2,091,895 | -2,928,653 | -7,884,835 | -14,643,265 | -20,500,571 | -102,502,855 |
