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 2,492,579, 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 | 2,492,579 | |
| -1 | -2,492,579 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,492,579.
Example:
1 x 2,492,579 = 2,492,579
and
-1 x -2,492,579 = 2,492,579
Notice both answers equal 2,492,579
With that explanation out of the way, let's continue. Next, we take the number 2,492,579 and divide it by 2:
2,492,579 ÷ 2 = 1,246,289.5
If the quotient is a whole number, then 2 and 1,246,289.5 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 | 2,492,579 | |
| -1 | -2,492,579 |
Now, we try dividing 2,492,579 by 3:
2,492,579 ÷ 3 = 830,859.6667
If the quotient is a whole number, then 3 and 830,859.6667 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 | 2,492,579 | |
| -1 | -2,492,579 |
Let's try dividing by 4:
2,492,579 ÷ 4 = 623,144.75
If the quotient is a whole number, then 4 and 623,144.75 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 | 2,492,579 | |
| -1 | 2,492,579 |
If you did it right, you will end up with this table:
| 1 | 23 | 29 | 37 | 101 | 667 | 851 | 1,073 | 2,323 | 2,929 | 3,737 | 24,679 | 67,367 | 85,951 | 108,373 | 2,492,579 |
| -1 | -23 | -29 | -37 | -101 | -667 | -851 | -1,073 | -2,323 | -2,929 | -3,737 | -24,679 | -67,367 | -85,951 | -108,373 | -2,492,579 |
