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 2,645,495, 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 | 2,645,495 | |
| -1 | -2,645,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,645,495.
Example:
1 x 2,645,495 = 2,645,495
and
-1 x -2,645,495 = 2,645,495
Notice both answers equal 2,645,495
With that explanation out of the way, let's continue. Next, we take the number 2,645,495 and divide it by 2:
2,645,495 ÷ 2 = 1,322,747.5
If the quotient is a whole number, then 2 and 1,322,747.5 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 | 2,645,495 | |
| -1 | -2,645,495 |
Now, we try dividing 2,645,495 by 3:
2,645,495 ÷ 3 = 881,831.6667
If the quotient is a whole number, then 3 and 881,831.6667 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 | 2,645,495 | |
| -1 | -2,645,495 |
Let's try dividing by 4:
2,645,495 ÷ 4 = 661,373.75
If the quotient is a whole number, then 4 and 661,373.75 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 | 2,645,495 | |
| -1 | 2,645,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 67 | 149 | 265 | 335 | 745 | 3,551 | 7,897 | 9,983 | 17,755 | 39,485 | 49,915 | 529,099 | 2,645,495 |
| -1 | -5 | -53 | -67 | -149 | -265 | -335 | -745 | -3,551 | -7,897 | -9,983 | -17,755 | -39,485 | -49,915 | -529,099 | -2,645,495 |
