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 12,772,025, 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 | 12,772,025 | |
| -1 | -12,772,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,772,025.
Example:
1 x 12,772,025 = 12,772,025
and
-1 x -12,772,025 = 12,772,025
Notice both answers equal 12,772,025
With that explanation out of the way, let's continue. Next, we take the number 12,772,025 and divide it by 2:
12,772,025 ÷ 2 = 6,386,012.5
If the quotient is a whole number, then 2 and 6,386,012.5 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 | 12,772,025 | |
| -1 | -12,772,025 |
Now, we try dividing 12,772,025 by 3:
12,772,025 ÷ 3 = 4,257,341.6667
If the quotient is a whole number, then 3 and 4,257,341.6667 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 | 12,772,025 | |
| -1 | -12,772,025 |
Let's try dividing by 4:
12,772,025 ÷ 4 = 3,193,006.25
If the quotient is a whole number, then 4 and 3,193,006.25 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 | 12,772,025 | |
| -1 | 12,772,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 59 | 175 | 295 | 413 | 1,237 | 1,475 | 2,065 | 6,185 | 8,659 | 10,325 | 30,925 | 43,295 | 72,983 | 216,475 | 364,915 | 510,881 | 1,824,575 | 2,554,405 | 12,772,025 |
| -1 | -5 | -7 | -25 | -35 | -59 | -175 | -295 | -413 | -1,237 | -1,475 | -2,065 | -6,185 | -8,659 | -10,325 | -30,925 | -43,295 | -72,983 | -216,475 | -364,915 | -510,881 | -1,824,575 | -2,554,405 | -12,772,025 |
