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 265,004,465, 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 | 265,004,465 | |
| -1 | -265,004,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,004,465.
Example:
1 x 265,004,465 = 265,004,465
and
-1 x -265,004,465 = 265,004,465
Notice both answers equal 265,004,465
With that explanation out of the way, let's continue. Next, we take the number 265,004,465 and divide it by 2:
265,004,465 ÷ 2 = 132,502,232.5
If the quotient is a whole number, then 2 and 132,502,232.5 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 | 265,004,465 | |
| -1 | -265,004,465 |
Now, we try dividing 265,004,465 by 3:
265,004,465 ÷ 3 = 88,334,821.6667
If the quotient is a whole number, then 3 and 88,334,821.6667 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 | 265,004,465 | |
| -1 | -265,004,465 |
Let's try dividing by 4:
265,004,465 ÷ 4 = 66,251,116.25
If the quotient is a whole number, then 4 and 66,251,116.25 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 | 265,004,465 | |
| -1 | 265,004,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 166,147 | 830,735 | 1,827,617 | 4,818,263 | 9,138,085 | 24,091,315 | 53,000,893 | 265,004,465 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -166,147 | -830,735 | -1,827,617 | -4,818,263 | -9,138,085 | -24,091,315 | -53,000,893 | -265,004,465 |
