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 4,778,125, 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 | 4,778,125 | |
| -1 | -4,778,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,778,125.
Example:
1 x 4,778,125 = 4,778,125
and
-1 x -4,778,125 = 4,778,125
Notice both answers equal 4,778,125
With that explanation out of the way, let's continue. Next, we take the number 4,778,125 and divide it by 2:
4,778,125 ÷ 2 = 2,389,062.5
If the quotient is a whole number, then 2 and 2,389,062.5 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 | 4,778,125 | |
| -1 | -4,778,125 |
Now, we try dividing 4,778,125 by 3:
4,778,125 ÷ 3 = 1,592,708.3333
If the quotient is a whole number, then 3 and 1,592,708.3333 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 | 4,778,125 | |
| -1 | -4,778,125 |
Let's try dividing by 4:
4,778,125 ÷ 4 = 1,194,531.25
If the quotient is a whole number, then 4 and 1,194,531.25 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 | 4,778,125 | |
| -1 | 4,778,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 139 | 275 | 625 | 695 | 1,375 | 1,529 | 3,125 | 3,475 | 6,875 | 7,645 | 17,375 | 34,375 | 38,225 | 86,875 | 191,125 | 434,375 | 955,625 | 4,778,125 |
| -1 | -5 | -11 | -25 | -55 | -125 | -139 | -275 | -625 | -695 | -1,375 | -1,529 | -3,125 | -3,475 | -6,875 | -7,645 | -17,375 | -34,375 | -38,225 | -86,875 | -191,125 | -434,375 | -955,625 | -4,778,125 |
