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 2,919,665, 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 | 2,919,665 | |
| -1 | -2,919,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,919,665.
Example:
1 x 2,919,665 = 2,919,665
and
-1 x -2,919,665 = 2,919,665
Notice both answers equal 2,919,665
With that explanation out of the way, let's continue. Next, we take the number 2,919,665 and divide it by 2:
2,919,665 ÷ 2 = 1,459,832.5
If the quotient is a whole number, then 2 and 1,459,832.5 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 | 2,919,665 | |
| -1 | -2,919,665 |
Now, we try dividing 2,919,665 by 3:
2,919,665 ÷ 3 = 973,221.6667
If the quotient is a whole number, then 3 and 973,221.6667 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 | 2,919,665 | |
| -1 | -2,919,665 |
Let's try dividing by 4:
2,919,665 ÷ 4 = 729,916.25
If the quotient is a whole number, then 4 and 729,916.25 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 | 2,919,665 | |
| -1 | 2,919,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 49 | 85 | 119 | 245 | 595 | 701 | 833 | 3,505 | 4,165 | 4,907 | 11,917 | 24,535 | 34,349 | 59,585 | 83,419 | 171,745 | 417,095 | 583,933 | 2,919,665 |
| -1 | -5 | -7 | -17 | -35 | -49 | -85 | -119 | -245 | -595 | -701 | -833 | -3,505 | -4,165 | -4,907 | -11,917 | -24,535 | -34,349 | -59,585 | -83,419 | -171,745 | -417,095 | -583,933 | -2,919,665 |
