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 10,054,625, 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 | 10,054,625 | |
| -1 | -10,054,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,054,625.
Example:
1 x 10,054,625 = 10,054,625
and
-1 x -10,054,625 = 10,054,625
Notice both answers equal 10,054,625
With that explanation out of the way, let's continue. Next, we take the number 10,054,625 and divide it by 2:
10,054,625 ÷ 2 = 5,027,312.5
If the quotient is a whole number, then 2 and 5,027,312.5 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 | 10,054,625 | |
| -1 | -10,054,625 |
Now, we try dividing 10,054,625 by 3:
10,054,625 ÷ 3 = 3,351,541.6667
If the quotient is a whole number, then 3 and 3,351,541.6667 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 | 10,054,625 | |
| -1 | -10,054,625 |
Let's try dividing by 4:
10,054,625 ÷ 4 = 2,513,656.25
If the quotient is a whole number, then 4 and 2,513,656.25 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 | 10,054,625 | |
| -1 | 10,054,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 11,491 | 57,455 | 80,437 | 287,275 | 402,185 | 1,436,375 | 2,010,925 | 10,054,625 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -11,491 | -57,455 | -80,437 | -287,275 | -402,185 | -1,436,375 | -2,010,925 | -10,054,625 |
