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 2,626,645, 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 | 2,626,645 | |
| -1 | -2,626,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,626,645.
Example:
1 x 2,626,645 = 2,626,645
and
-1 x -2,626,645 = 2,626,645
Notice both answers equal 2,626,645
With that explanation out of the way, let's continue. Next, we take the number 2,626,645 and divide it by 2:
2,626,645 ÷ 2 = 1,313,322.5
If the quotient is a whole number, then 2 and 1,313,322.5 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 | 2,626,645 | |
| -1 | -2,626,645 |
Now, we try dividing 2,626,645 by 3:
2,626,645 ÷ 3 = 875,548.3333
If the quotient is a whole number, then 3 and 875,548.3333 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 | 2,626,645 | |
| -1 | -2,626,645 |
Let's try dividing by 4:
2,626,645 ÷ 4 = 656,661.25
If the quotient is a whole number, then 4 and 656,661.25 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 | 2,626,645 | |
| -1 | 2,626,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 71 | 151 | 245 | 355 | 497 | 755 | 1,057 | 2,485 | 3,479 | 5,285 | 7,399 | 10,721 | 17,395 | 36,995 | 53,605 | 75,047 | 375,235 | 525,329 | 2,626,645 |
| -1 | -5 | -7 | -35 | -49 | -71 | -151 | -245 | -355 | -497 | -755 | -1,057 | -2,485 | -3,479 | -5,285 | -7,399 | -10,721 | -17,395 | -36,995 | -53,605 | -75,047 | -375,235 | -525,329 | -2,626,645 |
