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 25,000,523, 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 | 25,000,523 | |
| -1 | -25,000,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,000,523.
Example:
1 x 25,000,523 = 25,000,523
and
-1 x -25,000,523 = 25,000,523
Notice both answers equal 25,000,523
With that explanation out of the way, let's continue. Next, we take the number 25,000,523 and divide it by 2:
25,000,523 ÷ 2 = 12,500,261.5
If the quotient is a whole number, then 2 and 12,500,261.5 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 | 25,000,523 | |
| -1 | -25,000,523 |
Now, we try dividing 25,000,523 by 3:
25,000,523 ÷ 3 = 8,333,507.6667
If the quotient is a whole number, then 3 and 8,333,507.6667 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 | 25,000,523 | |
| -1 | -25,000,523 |
Let's try dividing by 4:
25,000,523 ÷ 4 = 6,250,130.75
If the quotient is a whole number, then 4 and 6,250,130.75 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 | 25,000,523 | |
| -1 | 25,000,523 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 29 | 157 | 289 | 323 | 493 | 551 | 2,669 | 2,983 | 4,553 | 5,491 | 8,381 | 9,367 | 45,373 | 50,711 | 77,401 | 86,507 | 159,239 | 862,087 | 1,315,817 | 1,470,619 | 25,000,523 |
| -1 | -17 | -19 | -29 | -157 | -289 | -323 | -493 | -551 | -2,669 | -2,983 | -4,553 | -5,491 | -8,381 | -9,367 | -45,373 | -50,711 | -77,401 | -86,507 | -159,239 | -862,087 | -1,315,817 | -1,470,619 | -25,000,523 |
