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 102,713,435, 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 | 102,713,435 | |
| -1 | -102,713,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,713,435.
Example:
1 x 102,713,435 = 102,713,435
and
-1 x -102,713,435 = 102,713,435
Notice both answers equal 102,713,435
With that explanation out of the way, let's continue. Next, we take the number 102,713,435 and divide it by 2:
102,713,435 ÷ 2 = 51,356,717.5
If the quotient is a whole number, then 2 and 51,356,717.5 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 | 102,713,435 | |
| -1 | -102,713,435 |
Now, we try dividing 102,713,435 by 3:
102,713,435 ÷ 3 = 34,237,811.6667
If the quotient is a whole number, then 3 and 34,237,811.6667 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 | 102,713,435 | |
| -1 | -102,713,435 |
Let's try dividing by 4:
102,713,435 ÷ 4 = 25,678,358.75
If the quotient is a whole number, then 4 and 25,678,358.75 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 | 102,713,435 | |
| -1 | 102,713,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 283 | 1,415 | 3,113 | 6,599 | 15,565 | 32,995 | 72,589 | 362,945 | 1,867,517 | 9,337,585 | 20,542,687 | 102,713,435 |
| -1 | -5 | -11 | -55 | -283 | -1,415 | -3,113 | -6,599 | -15,565 | -32,995 | -72,589 | -362,945 | -1,867,517 | -9,337,585 | -20,542,687 | -102,713,435 |
