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 264,660,445, 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 | 264,660,445 | |
| -1 | -264,660,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 264,660,445.
Example:
1 x 264,660,445 = 264,660,445
and
-1 x -264,660,445 = 264,660,445
Notice both answers equal 264,660,445
With that explanation out of the way, let's continue. Next, we take the number 264,660,445 and divide it by 2:
264,660,445 ÷ 2 = 132,330,222.5
If the quotient is a whole number, then 2 and 132,330,222.5 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 | 264,660,445 | |
| -1 | -264,660,445 |
Now, we try dividing 264,660,445 by 3:
264,660,445 ÷ 3 = 88,220,148.3333
If the quotient is a whole number, then 3 and 88,220,148.3333 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 | 264,660,445 | |
| -1 | -264,660,445 |
Let's try dividing by 4:
264,660,445 ÷ 4 = 66,165,111.25
If the quotient is a whole number, then 4 and 66,165,111.25 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 | 264,660,445 | |
| -1 | 264,660,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 185 | 259 | 1,295 | 204,371 | 1,021,855 | 1,430,597 | 7,152,985 | 7,561,727 | 37,808,635 | 52,932,089 | 264,660,445 |
| -1 | -5 | -7 | -35 | -37 | -185 | -259 | -1,295 | -204,371 | -1,021,855 | -1,430,597 | -7,152,985 | -7,561,727 | -37,808,635 | -52,932,089 | -264,660,445 |
