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 53,425,031, 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 | 53,425,031 | |
| -1 | -53,425,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,425,031.
Example:
1 x 53,425,031 = 53,425,031
and
-1 x -53,425,031 = 53,425,031
Notice both answers equal 53,425,031
With that explanation out of the way, let's continue. Next, we take the number 53,425,031 and divide it by 2:
53,425,031 ÷ 2 = 26,712,515.5
If the quotient is a whole number, then 2 and 26,712,515.5 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 | 53,425,031 | |
| -1 | -53,425,031 |
Now, we try dividing 53,425,031 by 3:
53,425,031 ÷ 3 = 17,808,343.6667
If the quotient is a whole number, then 3 and 17,808,343.6667 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 | 53,425,031 | |
| -1 | -53,425,031 |
Let's try dividing by 4:
53,425,031 ÷ 4 = 13,356,257.75
If the quotient is a whole number, then 4 and 13,356,257.75 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 | 53,425,031 | |
| -1 | 53,425,031 |
If you did it right, you will end up with this table:
| 1 | 11 | 59 | 263 | 313 | 649 | 2,893 | 3,443 | 15,517 | 18,467 | 82,319 | 170,687 | 203,137 | 905,509 | 4,856,821 | 53,425,031 |
| -1 | -11 | -59 | -263 | -313 | -649 | -2,893 | -3,443 | -15,517 | -18,467 | -82,319 | -170,687 | -203,137 | -905,509 | -4,856,821 | -53,425,031 |
