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 671,671, 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 | 671,671 | |
| -1 | -671,671 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 671,671.
Example:
1 x 671,671 = 671,671
and
-1 x -671,671 = 671,671
Notice both answers equal 671,671
With that explanation out of the way, let's continue. Next, we take the number 671,671 and divide it by 2:
671,671 ÷ 2 = 335,835.5
If the quotient is a whole number, then 2 and 335,835.5 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 | 671,671 | |
| -1 | -671,671 |
Now, we try dividing 671,671 by 3:
671,671 ÷ 3 = 223,890.3333
If the quotient is a whole number, then 3 and 223,890.3333 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 | 671,671 | |
| -1 | -671,671 |
Let's try dividing by 4:
671,671 ÷ 4 = 167,917.75
If the quotient is a whole number, then 4 and 167,917.75 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 | 671,671 | |
| -1 | 671,671 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 61 | 77 | 91 | 121 | 143 | 427 | 671 | 793 | 847 | 1,001 | 1,573 | 4,697 | 5,551 | 7,381 | 8,723 | 11,011 | 51,667 | 61,061 | 95,953 | 671,671 |
| -1 | -7 | -11 | -13 | -61 | -77 | -91 | -121 | -143 | -427 | -671 | -793 | -847 | -1,001 | -1,573 | -4,697 | -5,551 | -7,381 | -8,723 | -11,011 | -51,667 | -61,061 | -95,953 | -671,671 |
