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 2,796,619, 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 | 2,796,619 | |
| -1 | -2,796,619 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,796,619.
Example:
1 x 2,796,619 = 2,796,619
and
-1 x -2,796,619 = 2,796,619
Notice both answers equal 2,796,619
With that explanation out of the way, let's continue. Next, we take the number 2,796,619 and divide it by 2:
2,796,619 ÷ 2 = 1,398,309.5
If the quotient is a whole number, then 2 and 1,398,309.5 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 | 2,796,619 | |
| -1 | -2,796,619 |
Now, we try dividing 2,796,619 by 3:
2,796,619 ÷ 3 = 932,206.3333
If the quotient is a whole number, then 3 and 932,206.3333 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 | 2,796,619 | |
| -1 | -2,796,619 |
Let's try dividing by 4:
2,796,619 ÷ 4 = 699,154.75
If the quotient is a whole number, then 4 and 699,154.75 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 | 2,796,619 | |
| -1 | 2,796,619 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 71 | 119 | 331 | 497 | 1,207 | 2,317 | 5,627 | 8,449 | 23,501 | 39,389 | 164,507 | 399,517 | 2,796,619 |
| -1 | -7 | -17 | -71 | -119 | -331 | -497 | -1,207 | -2,317 | -5,627 | -8,449 | -23,501 | -39,389 | -164,507 | -399,517 | -2,796,619 |
