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 2,640,575, 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 | 2,640,575 | |
| -1 | -2,640,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,640,575.
Example:
1 x 2,640,575 = 2,640,575
and
-1 x -2,640,575 = 2,640,575
Notice both answers equal 2,640,575
With that explanation out of the way, let's continue. Next, we take the number 2,640,575 and divide it by 2:
2,640,575 ÷ 2 = 1,320,287.5
If the quotient is a whole number, then 2 and 1,320,287.5 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 | 2,640,575 | |
| -1 | -2,640,575 |
Now, we try dividing 2,640,575 by 3:
2,640,575 ÷ 3 = 880,191.6667
If the quotient is a whole number, then 3 and 880,191.6667 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 | 2,640,575 | |
| -1 | -2,640,575 |
Let's try dividing by 4:
2,640,575 ÷ 4 = 660,143.75
If the quotient is a whole number, then 4 and 660,143.75 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 | 2,640,575 | |
| -1 | 2,640,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 79 | 175 | 191 | 395 | 553 | 955 | 1,337 | 1,975 | 2,765 | 4,775 | 6,685 | 13,825 | 15,089 | 33,425 | 75,445 | 105,623 | 377,225 | 528,115 | 2,640,575 |
| -1 | -5 | -7 | -25 | -35 | -79 | -175 | -191 | -395 | -553 | -955 | -1,337 | -1,975 | -2,765 | -4,775 | -6,685 | -13,825 | -15,089 | -33,425 | -75,445 | -105,623 | -377,225 | -528,115 | -2,640,575 |
