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 101,730,655, 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 | 101,730,655 | |
| -1 | -101,730,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,730,655.
Example:
1 x 101,730,655 = 101,730,655
and
-1 x -101,730,655 = 101,730,655
Notice both answers equal 101,730,655
With that explanation out of the way, let's continue. Next, we take the number 101,730,655 and divide it by 2:
101,730,655 ÷ 2 = 50,865,327.5
If the quotient is a whole number, then 2 and 50,865,327.5 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 | 101,730,655 | |
| -1 | -101,730,655 |
Now, we try dividing 101,730,655 by 3:
101,730,655 ÷ 3 = 33,910,218.3333
If the quotient is a whole number, then 3 and 33,910,218.3333 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 | 101,730,655 | |
| -1 | -101,730,655 |
Let's try dividing by 4:
101,730,655 ÷ 4 = 25,432,663.75
If the quotient is a whole number, then 4 and 25,432,663.75 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 | 101,730,655 | |
| -1 | 101,730,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 82,373 | 411,865 | 1,070,849 | 1,565,087 | 5,354,245 | 7,825,435 | 20,346,131 | 101,730,655 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -82,373 | -411,865 | -1,070,849 | -1,565,087 | -5,354,245 | -7,825,435 | -20,346,131 | -101,730,655 |
