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 1,749,881, 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 | 1,749,881 | |
| -1 | -1,749,881 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,749,881.
Example:
1 x 1,749,881 = 1,749,881
and
-1 x -1,749,881 = 1,749,881
Notice both answers equal 1,749,881
With that explanation out of the way, let's continue. Next, we take the number 1,749,881 and divide it by 2:
1,749,881 ÷ 2 = 874,940.5
If the quotient is a whole number, then 2 and 874,940.5 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 | 1,749,881 | |
| -1 | -1,749,881 |
Now, we try dividing 1,749,881 by 3:
1,749,881 ÷ 3 = 583,293.6667
If the quotient is a whole number, then 3 and 583,293.6667 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 | 1,749,881 | |
| -1 | -1,749,881 |
Let's try dividing by 4:
1,749,881 ÷ 4 = 437,470.25
If the quotient is a whole number, then 4 and 437,470.25 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 | 1,749,881 | |
| -1 | 1,749,881 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 59 | 133 | 223 | 413 | 1,121 | 1,561 | 4,237 | 7,847 | 13,157 | 29,659 | 92,099 | 249,983 | 1,749,881 |
| -1 | -7 | -19 | -59 | -133 | -223 | -413 | -1,121 | -1,561 | -4,237 | -7,847 | -13,157 | -29,659 | -92,099 | -249,983 | -1,749,881 |
