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 7,090,895, 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 | 7,090,895 | |
| -1 | -7,090,895 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,090,895.
Example:
1 x 7,090,895 = 7,090,895
and
-1 x -7,090,895 = 7,090,895
Notice both answers equal 7,090,895
With that explanation out of the way, let's continue. Next, we take the number 7,090,895 and divide it by 2:
7,090,895 ÷ 2 = 3,545,447.5
If the quotient is a whole number, then 2 and 3,545,447.5 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 | 7,090,895 | |
| -1 | -7,090,895 |
Now, we try dividing 7,090,895 by 3:
7,090,895 ÷ 3 = 2,363,631.6667
If the quotient is a whole number, then 3 and 2,363,631.6667 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 | 7,090,895 | |
| -1 | -7,090,895 |
Let's try dividing by 4:
7,090,895 ÷ 4 = 1,772,723.75
If the quotient is a whole number, then 4 and 1,772,723.75 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 | 7,090,895 | |
| -1 | 7,090,895 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 10,663 | 53,315 | 74,641 | 202,597 | 373,205 | 1,012,985 | 1,418,179 | 7,090,895 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -10,663 | -53,315 | -74,641 | -202,597 | -373,205 | -1,012,985 | -1,418,179 | -7,090,895 |
