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 7,195,705, 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 | 7,195,705 | |
| -1 | -7,195,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,195,705.
Example:
1 x 7,195,705 = 7,195,705
and
-1 x -7,195,705 = 7,195,705
Notice both answers equal 7,195,705
With that explanation out of the way, let's continue. Next, we take the number 7,195,705 and divide it by 2:
7,195,705 ÷ 2 = 3,597,852.5
If the quotient is a whole number, then 2 and 3,597,852.5 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 | 7,195,705 | |
| -1 | -7,195,705 |
Now, we try dividing 7,195,705 by 3:
7,195,705 ÷ 3 = 2,398,568.3333
If the quotient is a whole number, then 3 and 2,398,568.3333 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 | 7,195,705 | |
| -1 | -7,195,705 |
Let's try dividing by 4:
7,195,705 ÷ 4 = 1,798,926.25
If the quotient is a whole number, then 4 and 1,798,926.25 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 | 7,195,705 | |
| -1 | 7,195,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 41 | 55 | 205 | 451 | 2,255 | 3,191 | 15,955 | 35,101 | 130,831 | 175,505 | 654,155 | 1,439,141 | 7,195,705 |
| -1 | -5 | -11 | -41 | -55 | -205 | -451 | -2,255 | -3,191 | -15,955 | -35,101 | -130,831 | -175,505 | -654,155 | -1,439,141 | -7,195,705 |
