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 5,671,625, 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 | 5,671,625 | |
| -1 | -5,671,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,671,625.
Example:
1 x 5,671,625 = 5,671,625
and
-1 x -5,671,625 = 5,671,625
Notice both answers equal 5,671,625
With that explanation out of the way, let's continue. Next, we take the number 5,671,625 and divide it by 2:
5,671,625 ÷ 2 = 2,835,812.5
If the quotient is a whole number, then 2 and 2,835,812.5 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 | 5,671,625 | |
| -1 | -5,671,625 |
Now, we try dividing 5,671,625 by 3:
5,671,625 ÷ 3 = 1,890,541.6667
If the quotient is a whole number, then 3 and 1,890,541.6667 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 | 5,671,625 | |
| -1 | -5,671,625 |
Let's try dividing by 4:
5,671,625 ÷ 4 = 1,417,906.25
If the quotient is a whole number, then 4 and 1,417,906.25 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 | 5,671,625 | |
| -1 | 5,671,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 125 | 157 | 289 | 425 | 785 | 1,445 | 2,125 | 2,669 | 3,925 | 7,225 | 13,345 | 19,625 | 36,125 | 45,373 | 66,725 | 226,865 | 333,625 | 1,134,325 | 5,671,625 |
| -1 | -5 | -17 | -25 | -85 | -125 | -157 | -289 | -425 | -785 | -1,445 | -2,125 | -2,669 | -3,925 | -7,225 | -13,345 | -19,625 | -36,125 | -45,373 | -66,725 | -226,865 | -333,625 | -1,134,325 | -5,671,625 |
