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 102,373,661, 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 | 102,373,661 | |
| -1 | -102,373,661 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,373,661.
Example:
1 x 102,373,661 = 102,373,661
and
-1 x -102,373,661 = 102,373,661
Notice both answers equal 102,373,661
With that explanation out of the way, let's continue. Next, we take the number 102,373,661 and divide it by 2:
102,373,661 ÷ 2 = 51,186,830.5
If the quotient is a whole number, then 2 and 51,186,830.5 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 | 102,373,661 | |
| -1 | -102,373,661 |
Now, we try dividing 102,373,661 by 3:
102,373,661 ÷ 3 = 34,124,553.6667
If the quotient is a whole number, then 3 and 34,124,553.6667 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 | 102,373,661 | |
| -1 | -102,373,661 |
Let's try dividing by 4:
102,373,661 ÷ 4 = 25,593,415.25
If the quotient is a whole number, then 4 and 25,593,415.25 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 | 102,373,661 | |
| -1 | 102,373,661 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 137 | 611 | 1,223 | 1,781 | 6,439 | 15,899 | 57,481 | 83,707 | 167,551 | 747,253 | 2,178,163 | 7,874,897 | 102,373,661 |
| -1 | -13 | -47 | -137 | -611 | -1,223 | -1,781 | -6,439 | -15,899 | -57,481 | -83,707 | -167,551 | -747,253 | -2,178,163 | -7,874,897 | -102,373,661 |
