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 265,333,651, 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 | 265,333,651 | |
| -1 | -265,333,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,333,651.
Example:
1 x 265,333,651 = 265,333,651
and
-1 x -265,333,651 = 265,333,651
Notice both answers equal 265,333,651
With that explanation out of the way, let's continue. Next, we take the number 265,333,651 and divide it by 2:
265,333,651 ÷ 2 = 132,666,825.5
If the quotient is a whole number, then 2 and 132,666,825.5 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 | 265,333,651 | |
| -1 | -265,333,651 |
Now, we try dividing 265,333,651 by 3:
265,333,651 ÷ 3 = 88,444,550.3333
If the quotient is a whole number, then 3 and 88,444,550.3333 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 | 265,333,651 | |
| -1 | -265,333,651 |
Let's try dividing by 4:
265,333,651 ÷ 4 = 66,333,412.75
If the quotient is a whole number, then 4 and 66,333,412.75 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 | 265,333,651 | |
| -1 | 265,333,651 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 209 | 223 | 2,453 | 4,237 | 5,693 | 46,607 | 62,623 | 108,167 | 1,189,837 | 1,269,539 | 13,964,929 | 24,121,241 | 265,333,651 |
| -1 | -11 | -19 | -209 | -223 | -2,453 | -4,237 | -5,693 | -46,607 | -62,623 | -108,167 | -1,189,837 | -1,269,539 | -13,964,929 | -24,121,241 | -265,333,651 |
