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 296,887,465, 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 | 296,887,465 | |
| -1 | -296,887,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 296,887,465.
Example:
1 x 296,887,465 = 296,887,465
and
-1 x -296,887,465 = 296,887,465
Notice both answers equal 296,887,465
With that explanation out of the way, let's continue. Next, we take the number 296,887,465 and divide it by 2:
296,887,465 ÷ 2 = 148,443,732.5
If the quotient is a whole number, then 2 and 148,443,732.5 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 | 296,887,465 | |
| -1 | -296,887,465 |
Now, we try dividing 296,887,465 by 3:
296,887,465 ÷ 3 = 98,962,488.3333
If the quotient is a whole number, then 3 and 98,962,488.3333 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 | 296,887,465 | |
| -1 | -296,887,465 |
Let's try dividing by 4:
296,887,465 ÷ 4 = 74,221,866.25
If the quotient is a whole number, then 4 and 74,221,866.25 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 | 296,887,465 | |
| -1 | 296,887,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 273,629 | 1,368,145 | 1,915,403 | 8,482,499 | 9,577,015 | 42,412,495 | 59,377,493 | 296,887,465 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -273,629 | -1,368,145 | -1,915,403 | -8,482,499 | -9,577,015 | -42,412,495 | -59,377,493 | -296,887,465 |
