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 2,514,631, 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 | 2,514,631 | |
| -1 | -2,514,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,514,631.
Example:
1 x 2,514,631 = 2,514,631
and
-1 x -2,514,631 = 2,514,631
Notice both answers equal 2,514,631
With that explanation out of the way, let's continue. Next, we take the number 2,514,631 and divide it by 2:
2,514,631 ÷ 2 = 1,257,315.5
If the quotient is a whole number, then 2 and 1,257,315.5 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 | 2,514,631 | |
| -1 | -2,514,631 |
Now, we try dividing 2,514,631 by 3:
2,514,631 ÷ 3 = 838,210.3333
If the quotient is a whole number, then 3 and 838,210.3333 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 | 2,514,631 | |
| -1 | -2,514,631 |
Let's try dividing by 4:
2,514,631 ÷ 4 = 628,657.75
If the quotient is a whole number, then 4 and 628,657.75 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 | 2,514,631 | |
| -1 | 2,514,631 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 37 | 49 | 73 | 133 | 259 | 511 | 703 | 931 | 1,387 | 1,813 | 2,701 | 3,577 | 4,921 | 9,709 | 18,907 | 34,447 | 51,319 | 67,963 | 132,349 | 359,233 | 2,514,631 |
| -1 | -7 | -19 | -37 | -49 | -73 | -133 | -259 | -511 | -703 | -931 | -1,387 | -1,813 | -2,701 | -3,577 | -4,921 | -9,709 | -18,907 | -34,447 | -51,319 | -67,963 | -132,349 | -359,233 | -2,514,631 |
