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 264,631,315, 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 | 264,631,315 | |
| -1 | -264,631,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 264,631,315.
Example:
1 x 264,631,315 = 264,631,315
and
-1 x -264,631,315 = 264,631,315
Notice both answers equal 264,631,315
With that explanation out of the way, let's continue. Next, we take the number 264,631,315 and divide it by 2:
264,631,315 ÷ 2 = 132,315,657.5
If the quotient is a whole number, then 2 and 132,315,657.5 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 | 264,631,315 | |
| -1 | -264,631,315 |
Now, we try dividing 264,631,315 by 3:
264,631,315 ÷ 3 = 88,210,438.3333
If the quotient is a whole number, then 3 and 88,210,438.3333 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 | 264,631,315 | |
| -1 | -264,631,315 |
Let's try dividing by 4:
264,631,315 ÷ 4 = 66,157,828.75
If the quotient is a whole number, then 4 and 66,157,828.75 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 | 264,631,315 | |
| -1 | 264,631,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 163 | 815 | 2,119 | 10,595 | 24,977 | 124,885 | 324,701 | 1,623,505 | 4,071,251 | 20,356,255 | 52,926,263 | 264,631,315 |
| -1 | -5 | -13 | -65 | -163 | -815 | -2,119 | -10,595 | -24,977 | -124,885 | -324,701 | -1,623,505 | -4,071,251 | -20,356,255 | -52,926,263 | -264,631,315 |
