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 102,156,103, 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 | 102,156,103 | |
| -1 | -102,156,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,156,103.
Example:
1 x 102,156,103 = 102,156,103
and
-1 x -102,156,103 = 102,156,103
Notice both answers equal 102,156,103
With that explanation out of the way, let's continue. Next, we take the number 102,156,103 and divide it by 2:
102,156,103 ÷ 2 = 51,078,051.5
If the quotient is a whole number, then 2 and 51,078,051.5 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 | 102,156,103 | |
| -1 | -102,156,103 |
Now, we try dividing 102,156,103 by 3:
102,156,103 ÷ 3 = 34,052,034.3333
If the quotient is a whole number, then 3 and 34,052,034.3333 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 | 102,156,103 | |
| -1 | -102,156,103 |
Let's try dividing by 4:
102,156,103 ÷ 4 = 25,539,025.75
If the quotient is a whole number, then 4 and 25,539,025.75 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 | 102,156,103 | |
| -1 | 102,156,103 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 317 | 2,219 | 2,423 | 6,023 | 16,961 | 42,161 | 46,037 | 322,259 | 768,091 | 5,376,637 | 14,593,729 | 102,156,103 |
| -1 | -7 | -19 | -133 | -317 | -2,219 | -2,423 | -6,023 | -16,961 | -42,161 | -46,037 | -322,259 | -768,091 | -5,376,637 | -14,593,729 | -102,156,103 |
