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 102,054,425, 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 | 102,054,425 | |
| -1 | -102,054,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,054,425.
Example:
1 x 102,054,425 = 102,054,425
and
-1 x -102,054,425 = 102,054,425
Notice both answers equal 102,054,425
With that explanation out of the way, let's continue. Next, we take the number 102,054,425 and divide it by 2:
102,054,425 ÷ 2 = 51,027,212.5
If the quotient is a whole number, then 2 and 51,027,212.5 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 | 102,054,425 | |
| -1 | -102,054,425 |
Now, we try dividing 102,054,425 by 3:
102,054,425 ÷ 3 = 34,018,141.6667
If the quotient is a whole number, then 3 and 34,018,141.6667 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 | 102,054,425 | |
| -1 | -102,054,425 |
Let's try dividing by 4:
102,054,425 ÷ 4 = 25,513,606.25
If the quotient is a whole number, then 4 and 25,513,606.25 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 | 102,054,425 | |
| -1 | 102,054,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 605 | 1,331 | 3,025 | 3,067 | 6,655 | 15,335 | 33,275 | 33,737 | 76,675 | 168,685 | 371,107 | 843,425 | 1,855,535 | 4,082,177 | 9,277,675 | 20,410,885 | 102,054,425 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -605 | -1,331 | -3,025 | -3,067 | -6,655 | -15,335 | -33,275 | -33,737 | -76,675 | -168,685 | -371,107 | -843,425 | -1,855,535 | -4,082,177 | -9,277,675 | -20,410,885 | -102,054,425 |
