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 326,346,455, 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 | 326,346,455 | |
| -1 | -326,346,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 326,346,455.
Example:
1 x 326,346,455 = 326,346,455
and
-1 x -326,346,455 = 326,346,455
Notice both answers equal 326,346,455
With that explanation out of the way, let's continue. Next, we take the number 326,346,455 and divide it by 2:
326,346,455 ÷ 2 = 163,173,227.5
If the quotient is a whole number, then 2 and 163,173,227.5 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 | 326,346,455 | |
| -1 | -326,346,455 |
Now, we try dividing 326,346,455 by 3:
326,346,455 ÷ 3 = 108,782,151.6667
If the quotient is a whole number, then 3 and 108,782,151.6667 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 | 326,346,455 | |
| -1 | -326,346,455 |
Let's try dividing by 4:
326,346,455 ÷ 4 = 81,586,613.75
If the quotient is a whole number, then 4 and 81,586,613.75 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 | 326,346,455 | |
| -1 | 326,346,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 83 | 155 | 415 | 2,573 | 12,865 | 25,367 | 126,835 | 786,377 | 2,105,461 | 3,931,885 | 10,527,305 | 65,269,291 | 326,346,455 |
| -1 | -5 | -31 | -83 | -155 | -415 | -2,573 | -12,865 | -25,367 | -126,835 | -786,377 | -2,105,461 | -3,931,885 | -10,527,305 | -65,269,291 | -326,346,455 |
