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 10,510,625, 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 | 10,510,625 | |
| -1 | -10,510,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,510,625.
Example:
1 x 10,510,625 = 10,510,625
and
-1 x -10,510,625 = 10,510,625
Notice both answers equal 10,510,625
With that explanation out of the way, let's continue. Next, we take the number 10,510,625 and divide it by 2:
10,510,625 ÷ 2 = 5,255,312.5
If the quotient is a whole number, then 2 and 5,255,312.5 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 | 10,510,625 | |
| -1 | -10,510,625 |
Now, we try dividing 10,510,625 by 3:
10,510,625 ÷ 3 = 3,503,541.6667
If the quotient is a whole number, then 3 and 3,503,541.6667 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 | 10,510,625 | |
| -1 | -10,510,625 |
Let's try dividing by 4:
10,510,625 ÷ 4 = 2,627,656.25
If the quotient is a whole number, then 4 and 2,627,656.25 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 | 10,510,625 | |
| -1 | 10,510,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 67 | 125 | 251 | 335 | 625 | 1,255 | 1,675 | 6,275 | 8,375 | 16,817 | 31,375 | 41,875 | 84,085 | 156,875 | 420,425 | 2,102,125 | 10,510,625 |
| -1 | -5 | -25 | -67 | -125 | -251 | -335 | -625 | -1,255 | -1,675 | -6,275 | -8,375 | -16,817 | -31,375 | -41,875 | -84,085 | -156,875 | -420,425 | -2,102,125 | -10,510,625 |
