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 265,524,215, 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 | 265,524,215 | |
| -1 | -265,524,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,524,215.
Example:
1 x 265,524,215 = 265,524,215
and
-1 x -265,524,215 = 265,524,215
Notice both answers equal 265,524,215
With that explanation out of the way, let's continue. Next, we take the number 265,524,215 and divide it by 2:
265,524,215 ÷ 2 = 132,762,107.5
If the quotient is a whole number, then 2 and 132,762,107.5 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 | 265,524,215 | |
| -1 | -265,524,215 |
Now, we try dividing 265,524,215 by 3:
265,524,215 ÷ 3 = 88,508,071.6667
If the quotient is a whole number, then 3 and 88,508,071.6667 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 | 265,524,215 | |
| -1 | -265,524,215 |
Let's try dividing by 4:
265,524,215 ÷ 4 = 66,381,053.75
If the quotient is a whole number, then 4 and 66,381,053.75 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 | 265,524,215 | |
| -1 | 265,524,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 103 | 121 | 515 | 605 | 1,133 | 4,261 | 5,665 | 12,463 | 21,305 | 46,871 | 62,315 | 234,355 | 438,883 | 515,581 | 2,194,415 | 2,577,905 | 4,827,713 | 24,138,565 | 53,104,843 | 265,524,215 |
| -1 | -5 | -11 | -55 | -103 | -121 | -515 | -605 | -1,133 | -4,261 | -5,665 | -12,463 | -21,305 | -46,871 | -62,315 | -234,355 | -438,883 | -515,581 | -2,194,415 | -2,577,905 | -4,827,713 | -24,138,565 | -53,104,843 | -265,524,215 |
