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 102,502,543, 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 | 102,502,543 | |
| -1 | -102,502,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,502,543.
Example:
1 x 102,502,543 = 102,502,543
and
-1 x -102,502,543 = 102,502,543
Notice both answers equal 102,502,543
With that explanation out of the way, let's continue. Next, we take the number 102,502,543 and divide it by 2:
102,502,543 ÷ 2 = 51,251,271.5
If the quotient is a whole number, then 2 and 51,251,271.5 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 | 102,502,543 | |
| -1 | -102,502,543 |
Now, we try dividing 102,502,543 by 3:
102,502,543 ÷ 3 = 34,167,514.3333
If the quotient is a whole number, then 3 and 34,167,514.3333 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 | 102,502,543 | |
| -1 | -102,502,543 |
Let's try dividing by 4:
102,502,543 ÷ 4 = 25,625,635.75
If the quotient is a whole number, then 4 and 25,625,635.75 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 | 102,502,543 | |
| -1 | 102,502,543 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 37 | 143 | 407 | 481 | 5,291 | 19,373 | 213,103 | 251,849 | 716,801 | 2,770,339 | 7,884,811 | 9,318,413 | 102,502,543 |
| -1 | -11 | -13 | -37 | -143 | -407 | -481 | -5,291 | -19,373 | -213,103 | -251,849 | -716,801 | -2,770,339 | -7,884,811 | -9,318,413 | -102,502,543 |
