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 670,354,715, 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 | 670,354,715 | |
| -1 | -670,354,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 670,354,715.
Example:
1 x 670,354,715 = 670,354,715
and
-1 x -670,354,715 = 670,354,715
Notice both answers equal 670,354,715
With that explanation out of the way, let's continue. Next, we take the number 670,354,715 and divide it by 2:
670,354,715 ÷ 2 = 335,177,357.5
If the quotient is a whole number, then 2 and 335,177,357.5 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 | 670,354,715 | |
| -1 | -670,354,715 |
Now, we try dividing 670,354,715 by 3:
670,354,715 ÷ 3 = 223,451,571.6667
If the quotient is a whole number, then 3 and 223,451,571.6667 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 | 670,354,715 | |
| -1 | -670,354,715 |
Let's try dividing by 4:
670,354,715 ÷ 4 = 167,588,678.75
If the quotient is a whole number, then 4 and 167,588,678.75 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 | 670,354,715 | |
| -1 | 670,354,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 41 | 185 | 205 | 1,517 | 7,585 | 88,379 | 441,895 | 3,270,023 | 3,623,539 | 16,350,115 | 18,117,695 | 134,070,943 | 670,354,715 |
| -1 | -5 | -37 | -41 | -185 | -205 | -1,517 | -7,585 | -88,379 | -441,895 | -3,270,023 | -3,623,539 | -16,350,115 | -18,117,695 | -134,070,943 | -670,354,715 |
