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 265,514,323, 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 | 265,514,323 | |
| -1 | -265,514,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,514,323.
Example:
1 x 265,514,323 = 265,514,323
and
-1 x -265,514,323 = 265,514,323
Notice both answers equal 265,514,323
With that explanation out of the way, let's continue. Next, we take the number 265,514,323 and divide it by 2:
265,514,323 ÷ 2 = 132,757,161.5
If the quotient is a whole number, then 2 and 132,757,161.5 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 | 265,514,323 | |
| -1 | -265,514,323 |
Now, we try dividing 265,514,323 by 3:
265,514,323 ÷ 3 = 88,504,774.3333
If the quotient is a whole number, then 3 and 88,504,774.3333 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 | 265,514,323 | |
| -1 | -265,514,323 |
Let's try dividing by 4:
265,514,323 ÷ 4 = 66,378,580.75
If the quotient is a whole number, then 4 and 66,378,580.75 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 | 265,514,323 | |
| -1 | 265,514,323 |
If you did it right, you will end up with this table:
| 1 | 23 | 89 | 151 | 859 | 2,047 | 3,473 | 13,439 | 19,757 | 76,451 | 129,709 | 309,097 | 1,758,373 | 2,983,307 | 11,544,101 | 265,514,323 |
| -1 | -23 | -89 | -151 | -859 | -2,047 | -3,473 | -13,439 | -19,757 | -76,451 | -129,709 | -309,097 | -1,758,373 | -2,983,307 | -11,544,101 | -265,514,323 |
