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 347,887,267, 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 | 347,887,267 | |
| -1 | -347,887,267 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 347,887,267.
Example:
1 x 347,887,267 = 347,887,267
and
-1 x -347,887,267 = 347,887,267
Notice both answers equal 347,887,267
With that explanation out of the way, let's continue. Next, we take the number 347,887,267 and divide it by 2:
347,887,267 ÷ 2 = 173,943,633.5
If the quotient is a whole number, then 2 and 173,943,633.5 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 | 347,887,267 | |
| -1 | -347,887,267 |
Now, we try dividing 347,887,267 by 3:
347,887,267 ÷ 3 = 115,962,422.3333
If the quotient is a whole number, then 3 and 115,962,422.3333 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 | 347,887,267 | |
| -1 | -347,887,267 |
Let's try dividing by 4:
347,887,267 ÷ 4 = 86,971,816.75
If the quotient is a whole number, then 4 and 86,971,816.75 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 | 347,887,267 | |
| -1 | 347,887,267 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 73 | 91 | 511 | 949 | 6,643 | 52,369 | 366,583 | 680,797 | 3,822,937 | 4,765,579 | 26,760,559 | 49,698,181 | 347,887,267 |
| -1 | -7 | -13 | -73 | -91 | -511 | -949 | -6,643 | -52,369 | -366,583 | -680,797 | -3,822,937 | -4,765,579 | -26,760,559 | -49,698,181 | -347,887,267 |
