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 25,077,065, 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 | 25,077,065 | |
| -1 | -25,077,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,077,065.
Example:
1 x 25,077,065 = 25,077,065
and
-1 x -25,077,065 = 25,077,065
Notice both answers equal 25,077,065
With that explanation out of the way, let's continue. Next, we take the number 25,077,065 and divide it by 2:
25,077,065 ÷ 2 = 12,538,532.5
If the quotient is a whole number, then 2 and 12,538,532.5 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 | 25,077,065 | |
| -1 | -25,077,065 |
Now, we try dividing 25,077,065 by 3:
25,077,065 ÷ 3 = 8,359,021.6667
If the quotient is a whole number, then 3 and 8,359,021.6667 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 | 25,077,065 | |
| -1 | -25,077,065 |
Let's try dividing by 4:
25,077,065 ÷ 4 = 6,269,266.25
If the quotient is a whole number, then 4 and 6,269,266.25 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 | 25,077,065 | |
| -1 | 25,077,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 59 | 65 | 169 | 295 | 503 | 767 | 845 | 2,515 | 3,835 | 6,539 | 9,971 | 29,677 | 32,695 | 49,855 | 85,007 | 148,385 | 385,801 | 425,035 | 1,929,005 | 5,015,413 | 25,077,065 |
| -1 | -5 | -13 | -59 | -65 | -169 | -295 | -503 | -767 | -845 | -2,515 | -3,835 | -6,539 | -9,971 | -29,677 | -32,695 | -49,855 | -85,007 | -148,385 | -385,801 | -425,035 | -1,929,005 | -5,015,413 | -25,077,065 |
