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 5,312,671, 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 | 5,312,671 | |
| -1 | -5,312,671 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,312,671.
Example:
1 x 5,312,671 = 5,312,671
and
-1 x -5,312,671 = 5,312,671
Notice both answers equal 5,312,671
With that explanation out of the way, let's continue. Next, we take the number 5,312,671 and divide it by 2:
5,312,671 ÷ 2 = 2,656,335.5
If the quotient is a whole number, then 2 and 2,656,335.5 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 | 5,312,671 | |
| -1 | -5,312,671 |
Now, we try dividing 5,312,671 by 3:
5,312,671 ÷ 3 = 1,770,890.3333
If the quotient is a whole number, then 3 and 1,770,890.3333 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 | 5,312,671 | |
| -1 | -5,312,671 |
Let's try dividing by 4:
5,312,671 ÷ 4 = 1,328,167.75
If the quotient is a whole number, then 4 and 1,328,167.75 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 | 5,312,671 | |
| -1 | 5,312,671 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 79 | 91 | 553 | 739 | 1,027 | 5,173 | 7,189 | 9,607 | 58,381 | 67,249 | 408,667 | 758,953 | 5,312,671 |
| -1 | -7 | -13 | -79 | -91 | -553 | -739 | -1,027 | -5,173 | -7,189 | -9,607 | -58,381 | -67,249 | -408,667 | -758,953 | -5,312,671 |
