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 1,375,699, 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 | 1,375,699 | |
| -1 | -1,375,699 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,375,699.
Example:
1 x 1,375,699 = 1,375,699
and
-1 x -1,375,699 = 1,375,699
Notice both answers equal 1,375,699
With that explanation out of the way, let's continue. Next, we take the number 1,375,699 and divide it by 2:
1,375,699 ÷ 2 = 687,849.5
If the quotient is a whole number, then 2 and 687,849.5 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 | 1,375,699 | |
| -1 | -1,375,699 |
Now, we try dividing 1,375,699 by 3:
1,375,699 ÷ 3 = 458,566.3333
If the quotient is a whole number, then 3 and 458,566.3333 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 | 1,375,699 | |
| -1 | -1,375,699 |
Let's try dividing by 4:
1,375,699 ÷ 4 = 343,924.75
If the quotient is a whole number, then 4 and 343,924.75 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 | 1,375,699 | |
| -1 | 1,375,699 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 43 | 107 | 299 | 559 | 989 | 1,391 | 2,461 | 4,601 | 12,857 | 31,993 | 59,813 | 105,823 | 1,375,699 |
| -1 | -13 | -23 | -43 | -107 | -299 | -559 | -989 | -1,391 | -2,461 | -4,601 | -12,857 | -31,993 | -59,813 | -105,823 | -1,375,699 |
