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 1,375,885, 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 | 1,375,885 | |
| -1 | -1,375,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,375,885.
Example:
1 x 1,375,885 = 1,375,885
and
-1 x -1,375,885 = 1,375,885
Notice both answers equal 1,375,885
With that explanation out of the way, let's continue. Next, we take the number 1,375,885 and divide it by 2:
1,375,885 ÷ 2 = 687,942.5
If the quotient is a whole number, then 2 and 687,942.5 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 | 1,375,885 | |
| -1 | -1,375,885 |
Now, we try dividing 1,375,885 by 3:
1,375,885 ÷ 3 = 458,628.3333
If the quotient is a whole number, then 3 and 458,628.3333 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 | 1,375,885 | |
| -1 | -1,375,885 |
Let's try dividing by 4:
1,375,885 ÷ 4 = 343,971.25
If the quotient is a whole number, then 4 and 343,971.25 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 | 1,375,885 | |
| -1 | 1,375,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 2,069 | 10,345 | 14,483 | 39,311 | 72,415 | 196,555 | 275,177 | 1,375,885 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -2,069 | -10,345 | -14,483 | -39,311 | -72,415 | -196,555 | -275,177 | -1,375,885 |
