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 265,080,629, 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 | 265,080,629 | |
| -1 | -265,080,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,080,629.
Example:
1 x 265,080,629 = 265,080,629
and
-1 x -265,080,629 = 265,080,629
Notice both answers equal 265,080,629
With that explanation out of the way, let's continue. Next, we take the number 265,080,629 and divide it by 2:
265,080,629 ÷ 2 = 132,540,314.5
If the quotient is a whole number, then 2 and 132,540,314.5 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 | 265,080,629 | |
| -1 | -265,080,629 |
Now, we try dividing 265,080,629 by 3:
265,080,629 ÷ 3 = 88,360,209.6667
If the quotient is a whole number, then 3 and 88,360,209.6667 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 | 265,080,629 | |
| -1 | -265,080,629 |
Let's try dividing by 4:
265,080,629 ÷ 4 = 66,270,157.25
If the quotient is a whole number, then 4 and 66,270,157.25 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 | 265,080,629 | |
| -1 | 265,080,629 |
If you did it right, you will end up with this table:
| 1 | 11 | 79 | 121 | 869 | 1,331 | 2,521 | 9,559 | 27,731 | 105,149 | 199,159 | 305,041 | 2,190,749 | 3,355,451 | 24,098,239 | 265,080,629 |
| -1 | -11 | -79 | -121 | -869 | -1,331 | -2,521 | -9,559 | -27,731 | -105,149 | -199,159 | -305,041 | -2,190,749 | -3,355,451 | -24,098,239 | -265,080,629 |
