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 1,827,419, 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 | 1,827,419 | |
| -1 | -1,827,419 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,827,419.
Example:
1 x 1,827,419 = 1,827,419
and
-1 x -1,827,419 = 1,827,419
Notice both answers equal 1,827,419
With that explanation out of the way, let's continue. Next, we take the number 1,827,419 and divide it by 2:
1,827,419 ÷ 2 = 913,709.5
If the quotient is a whole number, then 2 and 913,709.5 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 | 1,827,419 | |
| -1 | -1,827,419 |
Now, we try dividing 1,827,419 by 3:
1,827,419 ÷ 3 = 609,139.6667
If the quotient is a whole number, then 3 and 609,139.6667 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 | 1,827,419 | |
| -1 | -1,827,419 |
Let's try dividing by 4:
1,827,419 ÷ 4 = 456,854.75
If the quotient is a whole number, then 4 and 456,854.75 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 | 1,827,419 | |
| -1 | 1,827,419 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 31 | 233 | 253 | 341 | 713 | 2,563 | 5,359 | 7,223 | 7,843 | 58,949 | 79,453 | 166,129 | 1,827,419 |
| -1 | -11 | -23 | -31 | -233 | -253 | -341 | -713 | -2,563 | -5,359 | -7,223 | -7,843 | -58,949 | -79,453 | -166,129 | -1,827,419 |
