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 53,425,853, 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 | 53,425,853 | |
| -1 | -53,425,853 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,425,853.
Example:
1 x 53,425,853 = 53,425,853
and
-1 x -53,425,853 = 53,425,853
Notice both answers equal 53,425,853
With that explanation out of the way, let's continue. Next, we take the number 53,425,853 and divide it by 2:
53,425,853 ÷ 2 = 26,712,926.5
If the quotient is a whole number, then 2 and 26,712,926.5 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 | 53,425,853 | |
| -1 | -53,425,853 |
Now, we try dividing 53,425,853 by 3:
53,425,853 ÷ 3 = 17,808,617.6667
If the quotient is a whole number, then 3 and 17,808,617.6667 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 | 53,425,853 | |
| -1 | -53,425,853 |
Let's try dividing by 4:
53,425,853 ÷ 4 = 13,356,463.25
If the quotient is a whole number, then 4 and 13,356,463.25 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 | 53,425,853 | |
| -1 | 53,425,853 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 73 | 247 | 949 | 1,387 | 2,963 | 18,031 | 38,519 | 56,297 | 216,299 | 731,861 | 2,811,887 | 4,109,681 | 53,425,853 |
| -1 | -13 | -19 | -73 | -247 | -949 | -1,387 | -2,963 | -18,031 | -38,519 | -56,297 | -216,299 | -731,861 | -2,811,887 | -4,109,681 | -53,425,853 |
