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 101,238,709, 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 | 101,238,709 | |
| -1 | -101,238,709 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,238,709.
Example:
1 x 101,238,709 = 101,238,709
and
-1 x -101,238,709 = 101,238,709
Notice both answers equal 101,238,709
With that explanation out of the way, let's continue. Next, we take the number 101,238,709 and divide it by 2:
101,238,709 ÷ 2 = 50,619,354.5
If the quotient is a whole number, then 2 and 50,619,354.5 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 | 101,238,709 | |
| -1 | -101,238,709 |
Now, we try dividing 101,238,709 by 3:
101,238,709 ÷ 3 = 33,746,236.3333
If the quotient is a whole number, then 3 and 33,746,236.3333 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 | 101,238,709 | |
| -1 | -101,238,709 |
Let's try dividing by 4:
101,238,709 ÷ 4 = 25,309,677.25
If the quotient is a whole number, then 4 and 25,309,677.25 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 | 101,238,709 | |
| -1 | 101,238,709 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 23 | 143 | 253 | 299 | 3,289 | 30,781 | 338,591 | 400,153 | 707,963 | 4,401,683 | 7,787,593 | 9,203,519 | 101,238,709 |
| -1 | -11 | -13 | -23 | -143 | -253 | -299 | -3,289 | -30,781 | -338,591 | -400,153 | -707,963 | -4,401,683 | -7,787,593 | -9,203,519 | -101,238,709 |
