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 264,373,207, 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 | 264,373,207 | |
| -1 | -264,373,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 264,373,207.
Example:
1 x 264,373,207 = 264,373,207
and
-1 x -264,373,207 = 264,373,207
Notice both answers equal 264,373,207
With that explanation out of the way, let's continue. Next, we take the number 264,373,207 and divide it by 2:
264,373,207 ÷ 2 = 132,186,603.5
If the quotient is a whole number, then 2 and 132,186,603.5 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 | 264,373,207 | |
| -1 | -264,373,207 |
Now, we try dividing 264,373,207 by 3:
264,373,207 ÷ 3 = 88,124,402.3333
If the quotient is a whole number, then 3 and 88,124,402.3333 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 | 264,373,207 | |
| -1 | -264,373,207 |
Let's try dividing by 4:
264,373,207 ÷ 4 = 66,093,301.75
If the quotient is a whole number, then 4 and 66,093,301.75 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 | 264,373,207 | |
| -1 | 264,373,207 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 61 | 287 | 427 | 2,501 | 15,101 | 17,507 | 105,707 | 619,141 | 921,161 | 4,333,987 | 6,448,127 | 37,767,601 | 264,373,207 |
| -1 | -7 | -41 | -61 | -287 | -427 | -2,501 | -15,101 | -17,507 | -105,707 | -619,141 | -921,161 | -4,333,987 | -6,448,127 | -37,767,601 | -264,373,207 |
