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 3,959,599, 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 | 3,959,599 | |
| -1 | -3,959,599 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,959,599.
Example:
1 x 3,959,599 = 3,959,599
and
-1 x -3,959,599 = 3,959,599
Notice both answers equal 3,959,599
With that explanation out of the way, let's continue. Next, we take the number 3,959,599 and divide it by 2:
3,959,599 ÷ 2 = 1,979,799.5
If the quotient is a whole number, then 2 and 1,979,799.5 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 | 3,959,599 | |
| -1 | -3,959,599 |
Now, we try dividing 3,959,599 by 3:
3,959,599 ÷ 3 = 1,319,866.3333
If the quotient is a whole number, then 3 and 1,319,866.3333 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 | 3,959,599 | |
| -1 | -3,959,599 |
Let's try dividing by 4:
3,959,599 ÷ 4 = 989,899.75
If the quotient is a whole number, then 4 and 989,899.75 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 | 3,959,599 | |
| -1 | 3,959,599 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 71 | 217 | 257 | 497 | 1,799 | 2,201 | 7,967 | 15,407 | 18,247 | 55,769 | 127,729 | 565,657 | 3,959,599 |
| -1 | -7 | -31 | -71 | -217 | -257 | -497 | -1,799 | -2,201 | -7,967 | -15,407 | -18,247 | -55,769 | -127,729 | -565,657 | -3,959,599 |
