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 102,134,435, 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 | 102,134,435 | |
| -1 | -102,134,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,134,435.
Example:
1 x 102,134,435 = 102,134,435
and
-1 x -102,134,435 = 102,134,435
Notice both answers equal 102,134,435
With that explanation out of the way, let's continue. Next, we take the number 102,134,435 and divide it by 2:
102,134,435 ÷ 2 = 51,067,217.5
If the quotient is a whole number, then 2 and 51,067,217.5 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 | 102,134,435 | |
| -1 | -102,134,435 |
Now, we try dividing 102,134,435 by 3:
102,134,435 ÷ 3 = 34,044,811.6667
If the quotient is a whole number, then 3 and 34,044,811.6667 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 | 102,134,435 | |
| -1 | -102,134,435 |
Let's try dividing by 4:
102,134,435 ÷ 4 = 25,533,608.75
If the quotient is a whole number, then 4 and 25,533,608.75 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 | 102,134,435 | |
| -1 | 102,134,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 61 | 65 | 305 | 793 | 3,965 | 25,759 | 128,795 | 334,867 | 1,571,299 | 1,674,335 | 7,856,495 | 20,426,887 | 102,134,435 |
| -1 | -5 | -13 | -61 | -65 | -305 | -793 | -3,965 | -25,759 | -128,795 | -334,867 | -1,571,299 | -1,674,335 | -7,856,495 | -20,426,887 | -102,134,435 |
