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 264,364,045, 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 | 264,364,045 | |
| -1 | -264,364,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 264,364,045.
Example:
1 x 264,364,045 = 264,364,045
and
-1 x -264,364,045 = 264,364,045
Notice both answers equal 264,364,045
With that explanation out of the way, let's continue. Next, we take the number 264,364,045 and divide it by 2:
264,364,045 ÷ 2 = 132,182,022.5
If the quotient is a whole number, then 2 and 132,182,022.5 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 | 264,364,045 | |
| -1 | -264,364,045 |
Now, we try dividing 264,364,045 by 3:
264,364,045 ÷ 3 = 88,121,348.3333
If the quotient is a whole number, then 3 and 88,121,348.3333 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 | 264,364,045 | |
| -1 | -264,364,045 |
Let's try dividing by 4:
264,364,045 ÷ 4 = 66,091,011.25
If the quotient is a whole number, then 4 and 66,091,011.25 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 | 264,364,045 | |
| -1 | 264,364,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,229 | 3,911 | 6,145 | 13,519 | 19,555 | 43,021 | 67,595 | 215,105 | 4,806,619 | 24,033,095 | 52,872,809 | 264,364,045 |
| -1 | -5 | -11 | -55 | -1,229 | -3,911 | -6,145 | -13,519 | -19,555 | -43,021 | -67,595 | -215,105 | -4,806,619 | -24,033,095 | -52,872,809 | -264,364,045 |
