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 296,830,921, 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 | 296,830,921 | |
| -1 | -296,830,921 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 296,830,921.
Example:
1 x 296,830,921 = 296,830,921
and
-1 x -296,830,921 = 296,830,921
Notice both answers equal 296,830,921
With that explanation out of the way, let's continue. Next, we take the number 296,830,921 and divide it by 2:
296,830,921 ÷ 2 = 148,415,460.5
If the quotient is a whole number, then 2 and 148,415,460.5 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 | 296,830,921 | |
| -1 | -296,830,921 |
Now, we try dividing 296,830,921 by 3:
296,830,921 ÷ 3 = 98,943,640.3333
If the quotient is a whole number, then 3 and 98,943,640.3333 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 | 296,830,921 | |
| -1 | -296,830,921 |
Let's try dividing by 4:
296,830,921 ÷ 4 = 74,207,730.25
If the quotient is a whole number, then 4 and 74,207,730.25 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 | 296,830,921 | |
| -1 | 296,830,921 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 73 | 899 | 2,117 | 2,263 | 4,523 | 65,627 | 131,167 | 140,213 | 330,179 | 4,066,177 | 9,575,191 | 10,235,549 | 296,830,921 |
| -1 | -29 | -31 | -73 | -899 | -2,117 | -2,263 | -4,523 | -65,627 | -131,167 | -140,213 | -330,179 | -4,066,177 | -9,575,191 | -10,235,549 | -296,830,921 |
