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 265,055,063, 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 | 265,055,063 | |
| -1 | -265,055,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,055,063.
Example:
1 x 265,055,063 = 265,055,063
and
-1 x -265,055,063 = 265,055,063
Notice both answers equal 265,055,063
With that explanation out of the way, let's continue. Next, we take the number 265,055,063 and divide it by 2:
265,055,063 ÷ 2 = 132,527,531.5
If the quotient is a whole number, then 2 and 132,527,531.5 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 | 265,055,063 | |
| -1 | -265,055,063 |
Now, we try dividing 265,055,063 by 3:
265,055,063 ÷ 3 = 88,351,687.6667
If the quotient is a whole number, then 3 and 88,351,687.6667 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 | 265,055,063 | |
| -1 | -265,055,063 |
Let's try dividing by 4:
265,055,063 ÷ 4 = 66,263,765.75
If the quotient is a whole number, then 4 and 66,263,765.75 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 | 265,055,063 | |
| -1 | 265,055,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 239 | 637 | 1,673 | 1,741 | 3,107 | 11,711 | 12,187 | 21,749 | 22,633 | 85,309 | 152,243 | 158,431 | 416,099 | 1,109,017 | 2,912,693 | 5,409,287 | 20,388,851 | 37,865,009 | 265,055,063 |
| -1 | -7 | -13 | -49 | -91 | -239 | -637 | -1,673 | -1,741 | -3,107 | -11,711 | -12,187 | -21,749 | -22,633 | -85,309 | -152,243 | -158,431 | -416,099 | -1,109,017 | -2,912,693 | -5,409,287 | -20,388,851 | -37,865,009 | -265,055,063 |
