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 102,343,265, 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 | 102,343,265 | |
| -1 | -102,343,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,343,265.
Example:
1 x 102,343,265 = 102,343,265
and
-1 x -102,343,265 = 102,343,265
Notice both answers equal 102,343,265
With that explanation out of the way, let's continue. Next, we take the number 102,343,265 and divide it by 2:
102,343,265 ÷ 2 = 51,171,632.5
If the quotient is a whole number, then 2 and 51,171,632.5 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 | 102,343,265 | |
| -1 | -102,343,265 |
Now, we try dividing 102,343,265 by 3:
102,343,265 ÷ 3 = 34,114,421.6667
If the quotient is a whole number, then 3 and 34,114,421.6667 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 | 102,343,265 | |
| -1 | -102,343,265 |
Let's try dividing by 4:
102,343,265 ÷ 4 = 25,585,816.25
If the quotient is a whole number, then 4 and 25,585,816.25 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 | 102,343,265 | |
| -1 | 102,343,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 265 | 379 | 1,019 | 1,895 | 5,095 | 20,087 | 54,007 | 100,435 | 270,035 | 386,201 | 1,931,005 | 20,468,653 | 102,343,265 |
| -1 | -5 | -53 | -265 | -379 | -1,019 | -1,895 | -5,095 | -20,087 | -54,007 | -100,435 | -270,035 | -386,201 | -1,931,005 | -20,468,653 | -102,343,265 |
