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 7,378,195, 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 | 7,378,195 | |
| -1 | -7,378,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,378,195.
Example:
1 x 7,378,195 = 7,378,195
and
-1 x -7,378,195 = 7,378,195
Notice both answers equal 7,378,195
With that explanation out of the way, let's continue. Next, we take the number 7,378,195 and divide it by 2:
7,378,195 ÷ 2 = 3,689,097.5
If the quotient is a whole number, then 2 and 3,689,097.5 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 | 7,378,195 | |
| -1 | -7,378,195 |
Now, we try dividing 7,378,195 by 3:
7,378,195 ÷ 3 = 2,459,398.3333
If the quotient is a whole number, then 3 and 2,459,398.3333 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 | 7,378,195 | |
| -1 | -7,378,195 |
Let's try dividing by 4:
7,378,195 ÷ 4 = 1,844,548.75
If the quotient is a whole number, then 4 and 1,844,548.75 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 | 7,378,195 | |
| -1 | 7,378,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 163 | 815 | 823 | 1,793 | 4,115 | 8,965 | 9,053 | 45,265 | 134,149 | 670,745 | 1,475,639 | 7,378,195 |
| -1 | -5 | -11 | -55 | -163 | -815 | -823 | -1,793 | -4,115 | -8,965 | -9,053 | -45,265 | -134,149 | -670,745 | -1,475,639 | -7,378,195 |
