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 2,280,019, 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 | 2,280,019 | |
| -1 | -2,280,019 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,280,019.
Example:
1 x 2,280,019 = 2,280,019
and
-1 x -2,280,019 = 2,280,019
Notice both answers equal 2,280,019
With that explanation out of the way, let's continue. Next, we take the number 2,280,019 and divide it by 2:
2,280,019 ÷ 2 = 1,140,009.5
If the quotient is a whole number, then 2 and 1,140,009.5 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 | 2,280,019 | |
| -1 | -2,280,019 |
Now, we try dividing 2,280,019 by 3:
2,280,019 ÷ 3 = 760,006.3333
If the quotient is a whole number, then 3 and 760,006.3333 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 | 2,280,019 | |
| -1 | -2,280,019 |
Let's try dividing by 4:
2,280,019 ÷ 4 = 570,004.75
If the quotient is a whole number, then 4 and 570,004.75 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 | 2,280,019 | |
| -1 | 2,280,019 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 31 | 49 | 79 | 133 | 217 | 553 | 589 | 931 | 1,501 | 1,519 | 2,449 | 3,871 | 4,123 | 10,507 | 17,143 | 28,861 | 46,531 | 73,549 | 120,001 | 325,717 | 2,280,019 |
| -1 | -7 | -19 | -31 | -49 | -79 | -133 | -217 | -553 | -589 | -931 | -1,501 | -1,519 | -2,449 | -3,871 | -4,123 | -10,507 | -17,143 | -28,861 | -46,531 | -73,549 | -120,001 | -325,717 | -2,280,019 |
