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 53,425,385, 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 | 53,425,385 | |
| -1 | -53,425,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,425,385.
Example:
1 x 53,425,385 = 53,425,385
and
-1 x -53,425,385 = 53,425,385
Notice both answers equal 53,425,385
With that explanation out of the way, let's continue. Next, we take the number 53,425,385 and divide it by 2:
53,425,385 ÷ 2 = 26,712,692.5
If the quotient is a whole number, then 2 and 26,712,692.5 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 | 53,425,385 | |
| -1 | -53,425,385 |
Now, we try dividing 53,425,385 by 3:
53,425,385 ÷ 3 = 17,808,461.6667
If the quotient is a whole number, then 3 and 17,808,461.6667 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 | 53,425,385 | |
| -1 | -53,425,385 |
Let's try dividing by 4:
53,425,385 ÷ 4 = 13,356,346.25
If the quotient is a whole number, then 4 and 13,356,346.25 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 | 53,425,385 | |
| -1 | 53,425,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 59 | 65 | 295 | 767 | 3,835 | 13,931 | 69,655 | 181,103 | 821,929 | 905,515 | 4,109,645 | 10,685,077 | 53,425,385 |
| -1 | -5 | -13 | -59 | -65 | -295 | -767 | -3,835 | -13,931 | -69,655 | -181,103 | -821,929 | -905,515 | -4,109,645 | -10,685,077 | -53,425,385 |
