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 1,799,015, 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 | 1,799,015 | |
| -1 | -1,799,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,799,015.
Example:
1 x 1,799,015 = 1,799,015
and
-1 x -1,799,015 = 1,799,015
Notice both answers equal 1,799,015
With that explanation out of the way, let's continue. Next, we take the number 1,799,015 and divide it by 2:
1,799,015 ÷ 2 = 899,507.5
If the quotient is a whole number, then 2 and 899,507.5 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 | 1,799,015 | |
| -1 | -1,799,015 |
Now, we try dividing 1,799,015 by 3:
1,799,015 ÷ 3 = 599,671.6667
If the quotient is a whole number, then 3 and 599,671.6667 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 | 1,799,015 | |
| -1 | -1,799,015 |
Let's try dividing by 4:
1,799,015 ÷ 4 = 449,753.75
If the quotient is a whole number, then 4 and 449,753.75 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 | 1,799,015 | |
| -1 | 1,799,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 29 | 95 | 145 | 551 | 653 | 2,755 | 3,265 | 12,407 | 18,937 | 62,035 | 94,685 | 359,803 | 1,799,015 |
| -1 | -5 | -19 | -29 | -95 | -145 | -551 | -653 | -2,755 | -3,265 | -12,407 | -18,937 | -62,035 | -94,685 | -359,803 | -1,799,015 |
