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 326,518,805, 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 | 326,518,805 | |
| -1 | -326,518,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 326,518,805.
Example:
1 x 326,518,805 = 326,518,805
and
-1 x -326,518,805 = 326,518,805
Notice both answers equal 326,518,805
With that explanation out of the way, let's continue. Next, we take the number 326,518,805 and divide it by 2:
326,518,805 ÷ 2 = 163,259,402.5
If the quotient is a whole number, then 2 and 163,259,402.5 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 | 326,518,805 | |
| -1 | -326,518,805 |
Now, we try dividing 326,518,805 by 3:
326,518,805 ÷ 3 = 108,839,601.6667
If the quotient is a whole number, then 3 and 108,839,601.6667 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 | 326,518,805 | |
| -1 | -326,518,805 |
Let's try dividing by 4:
326,518,805 ÷ 4 = 81,629,701.25
If the quotient is a whole number, then 4 and 81,629,701.25 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 | 326,518,805 | |
| -1 | 326,518,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 335 | 433 | 2,165 | 2,251 | 11,255 | 29,011 | 145,055 | 150,817 | 754,085 | 974,683 | 4,873,415 | 65,303,761 | 326,518,805 |
| -1 | -5 | -67 | -335 | -433 | -2,165 | -2,251 | -11,255 | -29,011 | -145,055 | -150,817 | -754,085 | -974,683 | -4,873,415 | -65,303,761 | -326,518,805 |
