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 102,358,073, 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 | 102,358,073 | |
| -1 | -102,358,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,358,073.
Example:
1 x 102,358,073 = 102,358,073
and
-1 x -102,358,073 = 102,358,073
Notice both answers equal 102,358,073
With that explanation out of the way, let's continue. Next, we take the number 102,358,073 and divide it by 2:
102,358,073 ÷ 2 = 51,179,036.5
If the quotient is a whole number, then 2 and 51,179,036.5 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 | 102,358,073 | |
| -1 | -102,358,073 |
Now, we try dividing 102,358,073 by 3:
102,358,073 ÷ 3 = 34,119,357.6667
If the quotient is a whole number, then 3 and 34,119,357.6667 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 | 102,358,073 | |
| -1 | -102,358,073 |
Let's try dividing by 4:
102,358,073 ÷ 4 = 25,589,518.25
If the quotient is a whole number, then 4 and 25,589,518.25 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 | 102,358,073 | |
| -1 | 102,358,073 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 71 | 437 | 1,349 | 1,633 | 3,299 | 31,027 | 62,681 | 75,877 | 234,229 | 1,441,663 | 4,450,351 | 5,387,267 | 102,358,073 |
| -1 | -19 | -23 | -71 | -437 | -1,349 | -1,633 | -3,299 | -31,027 | -62,681 | -75,877 | -234,229 | -1,441,663 | -4,450,351 | -5,387,267 | -102,358,073 |
