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 6,716,185, 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 | 6,716,185 | |
| -1 | -6,716,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,716,185.
Example:
1 x 6,716,185 = 6,716,185
and
-1 x -6,716,185 = 6,716,185
Notice both answers equal 6,716,185
With that explanation out of the way, let's continue. Next, we take the number 6,716,185 and divide it by 2:
6,716,185 ÷ 2 = 3,358,092.5
If the quotient is a whole number, then 2 and 3,358,092.5 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 | 6,716,185 | |
| -1 | -6,716,185 |
Now, we try dividing 6,716,185 by 3:
6,716,185 ÷ 3 = 2,238,728.3333
If the quotient is a whole number, then 3 and 2,238,728.3333 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 | 6,716,185 | |
| -1 | -6,716,185 |
Let's try dividing by 4:
6,716,185 ÷ 4 = 1,679,046.25
If the quotient is a whole number, then 4 and 1,679,046.25 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 | 6,716,185 | |
| -1 | 6,716,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 79 | 245 | 347 | 395 | 553 | 1,735 | 2,429 | 2,765 | 3,871 | 12,145 | 17,003 | 19,355 | 27,413 | 85,015 | 137,065 | 191,891 | 959,455 | 1,343,237 | 6,716,185 |
| -1 | -5 | -7 | -35 | -49 | -79 | -245 | -347 | -395 | -553 | -1,735 | -2,429 | -2,765 | -3,871 | -12,145 | -17,003 | -19,355 | -27,413 | -85,015 | -137,065 | -191,891 | -959,455 | -1,343,237 | -6,716,185 |
