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 1,375,615, 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 | 1,375,615 | |
| -1 | -1,375,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,375,615.
Example:
1 x 1,375,615 = 1,375,615
and
-1 x -1,375,615 = 1,375,615
Notice both answers equal 1,375,615
With that explanation out of the way, let's continue. Next, we take the number 1,375,615 and divide it by 2:
1,375,615 ÷ 2 = 687,807.5
If the quotient is a whole number, then 2 and 687,807.5 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 | 1,375,615 | |
| -1 | -1,375,615 |
Now, we try dividing 1,375,615 by 3:
1,375,615 ÷ 3 = 458,538.3333
If the quotient is a whole number, then 3 and 458,538.3333 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 | 1,375,615 | |
| -1 | -1,375,615 |
Let's try dividing by 4:
1,375,615 ÷ 4 = 343,903.75
If the quotient is a whole number, then 4 and 343,903.75 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 | 1,375,615 | |
| -1 | 1,375,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 53 | 145 | 179 | 265 | 895 | 1,537 | 5,191 | 7,685 | 9,487 | 25,955 | 47,435 | 275,123 | 1,375,615 |
| -1 | -5 | -29 | -53 | -145 | -179 | -265 | -895 | -1,537 | -5,191 | -7,685 | -9,487 | -25,955 | -47,435 | -275,123 | -1,375,615 |
