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 2,572,825, 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 | 2,572,825 | |
-1 | -2,572,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,572,825.
Example:
1 x 2,572,825 = 2,572,825
and
-1 x -2,572,825 = 2,572,825
Notice both answers equal 2,572,825
With that explanation out of the way, let's continue. Next, we take the number 2,572,825 and divide it by 2:
2,572,825 ÷ 2 = 1,286,412.5
If the quotient is a whole number, then 2 and 1,286,412.5 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 | 2,572,825 | |
-1 | -2,572,825 |
Now, we try dividing 2,572,825 by 3:
2,572,825 ÷ 3 = 857,608.3333
If the quotient is a whole number, then 3 and 857,608.3333 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 | 2,572,825 | |
-1 | -2,572,825 |
Let's try dividing by 4:
2,572,825 ÷ 4 = 643,206.25
If the quotient is a whole number, then 4 and 643,206.25 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 | 2,572,825 | |
-1 | 2,572,825 |
If you did it right, you will end up with this table:
1 | 5 | 25 | 102,913 | 514,565 | 2,572,825 |
-1 | -5 | -25 | -102,913 | -514,565 | -2,572,825 |
