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 4,752,979, 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 | 4,752,979 | |
| -1 | -4,752,979 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,752,979.
Example:
1 x 4,752,979 = 4,752,979
and
-1 x -4,752,979 = 4,752,979
Notice both answers equal 4,752,979
With that explanation out of the way, let's continue. Next, we take the number 4,752,979 and divide it by 2:
4,752,979 ÷ 2 = 2,376,489.5
If the quotient is a whole number, then 2 and 2,376,489.5 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 | 4,752,979 | |
| -1 | -4,752,979 |
Now, we try dividing 4,752,979 by 3:
4,752,979 ÷ 3 = 1,584,326.3333
If the quotient is a whole number, then 3 and 1,584,326.3333 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 | 4,752,979 | |
| -1 | -4,752,979 |
Let's try dividing by 4:
4,752,979 ÷ 4 = 1,188,244.75
If the quotient is a whole number, then 4 and 1,188,244.75 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 | 4,752,979 | |
| -1 | 4,752,979 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,309 | 3,631 | 25,417 | 39,941 | 61,727 | 279,587 | 432,089 | 678,997 | 4,752,979 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,309 | -3,631 | -25,417 | -39,941 | -61,727 | -279,587 | -432,089 | -678,997 | -4,752,979 |
