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 2,534,675, 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 | 2,534,675 | |
| -1 | -2,534,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,534,675.
Example:
1 x 2,534,675 = 2,534,675
and
-1 x -2,534,675 = 2,534,675
Notice both answers equal 2,534,675
With that explanation out of the way, let's continue. Next, we take the number 2,534,675 and divide it by 2:
2,534,675 ÷ 2 = 1,267,337.5
If the quotient is a whole number, then 2 and 1,267,337.5 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 | 2,534,675 | |
| -1 | -2,534,675 |
Now, we try dividing 2,534,675 by 3:
2,534,675 ÷ 3 = 844,891.6667
If the quotient is a whole number, then 3 and 844,891.6667 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 | 2,534,675 | |
| -1 | -2,534,675 |
Let's try dividing by 4:
2,534,675 ÷ 4 = 633,668.75
If the quotient is a whole number, then 4 and 633,668.75 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 | 2,534,675 | |
| -1 | 2,534,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 143 | 275 | 325 | 709 | 715 | 3,545 | 3,575 | 7,799 | 9,217 | 17,725 | 38,995 | 46,085 | 101,387 | 194,975 | 230,425 | 506,935 | 2,534,675 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -143 | -275 | -325 | -709 | -715 | -3,545 | -3,575 | -7,799 | -9,217 | -17,725 | -38,995 | -46,085 | -101,387 | -194,975 | -230,425 | -506,935 | -2,534,675 |
