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 670,266,727, 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 | 670,266,727 | |
| -1 | -670,266,727 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 670,266,727.
Example:
1 x 670,266,727 = 670,266,727
and
-1 x -670,266,727 = 670,266,727
Notice both answers equal 670,266,727
With that explanation out of the way, let's continue. Next, we take the number 670,266,727 and divide it by 2:
670,266,727 ÷ 2 = 335,133,363.5
If the quotient is a whole number, then 2 and 335,133,363.5 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 | 670,266,727 | |
| -1 | -670,266,727 |
Now, we try dividing 670,266,727 by 3:
670,266,727 ÷ 3 = 223,422,242.3333
If the quotient is a whole number, then 3 and 223,422,242.3333 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 | 670,266,727 | |
| -1 | -670,266,727 |
Let's try dividing by 4:
670,266,727 ÷ 4 = 167,566,681.75
If the quotient is a whole number, then 4 and 167,566,681.75 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 | 670,266,727 | |
| -1 | 670,266,727 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 67 | 767 | 871 | 3,953 | 13,043 | 51,389 | 169,559 | 769,537 | 873,881 | 10,003,981 | 11,360,453 | 51,558,979 | 670,266,727 |
| -1 | -13 | -59 | -67 | -767 | -871 | -3,953 | -13,043 | -51,389 | -169,559 | -769,537 | -873,881 | -10,003,981 | -11,360,453 | -51,558,979 | -670,266,727 |
