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 102,684,043, 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 | 102,684,043 | |
| -1 | -102,684,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,684,043.
Example:
1 x 102,684,043 = 102,684,043
and
-1 x -102,684,043 = 102,684,043
Notice both answers equal 102,684,043
With that explanation out of the way, let's continue. Next, we take the number 102,684,043 and divide it by 2:
102,684,043 ÷ 2 = 51,342,021.5
If the quotient is a whole number, then 2 and 51,342,021.5 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 | 102,684,043 | |
| -1 | -102,684,043 |
Now, we try dividing 102,684,043 by 3:
102,684,043 ÷ 3 = 34,228,014.3333
If the quotient is a whole number, then 3 and 34,228,014.3333 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 | 102,684,043 | |
| -1 | -102,684,043 |
Let's try dividing by 4:
102,684,043 ÷ 4 = 25,671,010.75
If the quotient is a whole number, then 4 and 25,671,010.75 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 | 102,684,043 | |
| -1 | 102,684,043 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 43 | 77 | 301 | 473 | 3,311 | 31,013 | 217,091 | 341,143 | 1,333,559 | 2,388,001 | 9,334,913 | 14,669,149 | 102,684,043 |
| -1 | -7 | -11 | -43 | -77 | -301 | -473 | -3,311 | -31,013 | -217,091 | -341,143 | -1,333,559 | -2,388,001 | -9,334,913 | -14,669,149 | -102,684,043 |
