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 347,088,745, 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 | 347,088,745 | |
| -1 | -347,088,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 347,088,745.
Example:
1 x 347,088,745 = 347,088,745
and
-1 x -347,088,745 = 347,088,745
Notice both answers equal 347,088,745
With that explanation out of the way, let's continue. Next, we take the number 347,088,745 and divide it by 2:
347,088,745 ÷ 2 = 173,544,372.5
If the quotient is a whole number, then 2 and 173,544,372.5 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 | 347,088,745 | |
| -1 | -347,088,745 |
Now, we try dividing 347,088,745 by 3:
347,088,745 ÷ 3 = 115,696,248.3333
If the quotient is a whole number, then 3 and 115,696,248.3333 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 | 347,088,745 | |
| -1 | -347,088,745 |
Let's try dividing by 4:
347,088,745 ÷ 4 = 86,772,186.25
If the quotient is a whole number, then 4 and 86,772,186.25 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 | 347,088,745 | |
| -1 | 347,088,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 85 | 115 | 391 | 1,955 | 177,539 | 887,695 | 3,018,163 | 4,083,397 | 15,090,815 | 20,416,985 | 69,417,749 | 347,088,745 |
| -1 | -5 | -17 | -23 | -85 | -115 | -391 | -1,955 | -177,539 | -887,695 | -3,018,163 | -4,083,397 | -15,090,815 | -20,416,985 | -69,417,749 | -347,088,745 |
