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 65,073,125, 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 | 65,073,125 | |
| -1 | -65,073,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,073,125.
Example:
1 x 65,073,125 = 65,073,125
and
-1 x -65,073,125 = 65,073,125
Notice both answers equal 65,073,125
With that explanation out of the way, let's continue. Next, we take the number 65,073,125 and divide it by 2:
65,073,125 ÷ 2 = 32,536,562.5
If the quotient is a whole number, then 2 and 32,536,562.5 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 | 65,073,125 | |
| -1 | -65,073,125 |
Now, we try dividing 65,073,125 by 3:
65,073,125 ÷ 3 = 21,691,041.6667
If the quotient is a whole number, then 3 and 21,691,041.6667 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 | 65,073,125 | |
| -1 | -65,073,125 |
Let's try dividing by 4:
65,073,125 ÷ 4 = 16,268,281.25
If the quotient is a whole number, then 4 and 16,268,281.25 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 | 65,073,125 | |
| -1 | 65,073,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 625 | 1,625 | 8,009 | 8,125 | 40,045 | 104,117 | 200,225 | 520,585 | 1,001,125 | 2,602,925 | 5,005,625 | 13,014,625 | 65,073,125 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -625 | -1,625 | -8,009 | -8,125 | -40,045 | -104,117 | -200,225 | -520,585 | -1,001,125 | -2,602,925 | -5,005,625 | -13,014,625 | -65,073,125 |
