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 265,550,525, 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 | 265,550,525 | |
| -1 | -265,550,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,550,525.
Example:
1 x 265,550,525 = 265,550,525
and
-1 x -265,550,525 = 265,550,525
Notice both answers equal 265,550,525
With that explanation out of the way, let's continue. Next, we take the number 265,550,525 and divide it by 2:
265,550,525 ÷ 2 = 132,775,262.5
If the quotient is a whole number, then 2 and 132,775,262.5 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 | 265,550,525 | |
| -1 | -265,550,525 |
Now, we try dividing 265,550,525 by 3:
265,550,525 ÷ 3 = 88,516,841.6667
If the quotient is a whole number, then 3 and 88,516,841.6667 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 | 265,550,525 | |
| -1 | -265,550,525 |
Let's try dividing by 4:
265,550,525 ÷ 4 = 66,387,631.25
If the quotient is a whole number, then 4 and 66,387,631.25 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 | 265,550,525 | |
| -1 | 265,550,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 137 | 575 | 685 | 3,151 | 3,371 | 3,425 | 15,755 | 16,855 | 77,533 | 78,775 | 84,275 | 387,665 | 461,827 | 1,938,325 | 2,309,135 | 10,622,021 | 11,545,675 | 53,110,105 | 265,550,525 |
| -1 | -5 | -23 | -25 | -115 | -137 | -575 | -685 | -3,151 | -3,371 | -3,425 | -15,755 | -16,855 | -77,533 | -78,775 | -84,275 | -387,665 | -461,827 | -1,938,325 | -2,309,135 | -10,622,021 | -11,545,675 | -53,110,105 | -265,550,525 |
