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 2,830,525, 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 | 2,830,525 | |
| -1 | -2,830,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,830,525.
Example:
1 x 2,830,525 = 2,830,525
and
-1 x -2,830,525 = 2,830,525
Notice both answers equal 2,830,525
With that explanation out of the way, let's continue. Next, we take the number 2,830,525 and divide it by 2:
2,830,525 ÷ 2 = 1,415,262.5
If the quotient is a whole number, then 2 and 1,415,262.5 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 | 2,830,525 | |
| -1 | -2,830,525 |
Now, we try dividing 2,830,525 by 3:
2,830,525 ÷ 3 = 943,508.3333
If the quotient is a whole number, then 3 and 943,508.3333 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 | 2,830,525 | |
| -1 | -2,830,525 |
Let's try dividing by 4:
2,830,525 ÷ 4 = 707,631.25
If the quotient is a whole number, then 4 and 707,631.25 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 | 2,830,525 | |
| -1 | 2,830,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 59 | 95 | 101 | 295 | 475 | 505 | 1,121 | 1,475 | 1,919 | 2,525 | 5,605 | 5,959 | 9,595 | 28,025 | 29,795 | 47,975 | 113,221 | 148,975 | 566,105 | 2,830,525 |
| -1 | -5 | -19 | -25 | -59 | -95 | -101 | -295 | -475 | -505 | -1,121 | -1,475 | -1,919 | -2,525 | -5,605 | -5,959 | -9,595 | -28,025 | -29,795 | -47,975 | -113,221 | -148,975 | -566,105 | -2,830,525 |
