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 670,275,571, 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 | 670,275,571 | |
| -1 | -670,275,571 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 670,275,571.
Example:
1 x 670,275,571 = 670,275,571
and
-1 x -670,275,571 = 670,275,571
Notice both answers equal 670,275,571
With that explanation out of the way, let's continue. Next, we take the number 670,275,571 and divide it by 2:
670,275,571 ÷ 2 = 335,137,785.5
If the quotient is a whole number, then 2 and 335,137,785.5 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 | 670,275,571 | |
| -1 | -670,275,571 |
Now, we try dividing 670,275,571 by 3:
670,275,571 ÷ 3 = 223,425,190.3333
If the quotient is a whole number, then 3 and 223,425,190.3333 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 | 670,275,571 | |
| -1 | -670,275,571 |
Let's try dividing by 4:
670,275,571 ÷ 4 = 167,568,892.75
If the quotient is a whole number, then 4 and 167,568,892.75 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 | 670,275,571 | |
| -1 | 670,275,571 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 71 | 469 | 497 | 4,757 | 20,129 | 33,299 | 140,903 | 1,348,643 | 1,429,159 | 9,440,501 | 10,004,113 | 95,753,653 | 670,275,571 |
| -1 | -7 | -67 | -71 | -469 | -497 | -4,757 | -20,129 | -33,299 | -140,903 | -1,348,643 | -1,429,159 | -9,440,501 | -10,004,113 | -95,753,653 | -670,275,571 |
