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 670,003,711, 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 | 670,003,711 | |
| -1 | -670,003,711 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 670,003,711.
Example:
1 x 670,003,711 = 670,003,711
and
-1 x -670,003,711 = 670,003,711
Notice both answers equal 670,003,711
With that explanation out of the way, let's continue. Next, we take the number 670,003,711 and divide it by 2:
670,003,711 ÷ 2 = 335,001,855.5
If the quotient is a whole number, then 2 and 335,001,855.5 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 | 670,003,711 | |
| -1 | -670,003,711 |
Now, we try dividing 670,003,711 by 3:
670,003,711 ÷ 3 = 223,334,570.3333
If the quotient is a whole number, then 3 and 223,334,570.3333 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 | 670,003,711 | |
| -1 | -670,003,711 |
Let's try dividing by 4:
670,003,711 ÷ 4 = 167,500,927.75
If the quotient is a whole number, then 4 and 167,500,927.75 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 | 670,003,711 | |
| -1 | 670,003,711 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 169 | 221 | 2,197 | 2,873 | 17,939 | 37,349 | 233,207 | 304,963 | 3,031,691 | 3,964,519 | 39,411,983 | 51,538,747 | 670,003,711 |
| -1 | -13 | -17 | -169 | -221 | -2,197 | -2,873 | -17,939 | -37,349 | -233,207 | -304,963 | -3,031,691 | -3,964,519 | -39,411,983 | -51,538,747 | -670,003,711 |
