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 2,679,485, 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 | 2,679,485 | |
| -1 | -2,679,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,679,485.
Example:
1 x 2,679,485 = 2,679,485
and
-1 x -2,679,485 = 2,679,485
Notice both answers equal 2,679,485
With that explanation out of the way, let's continue. Next, we take the number 2,679,485 and divide it by 2:
2,679,485 ÷ 2 = 1,339,742.5
If the quotient is a whole number, then 2 and 1,339,742.5 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 | 2,679,485 | |
| -1 | -2,679,485 |
Now, we try dividing 2,679,485 by 3:
2,679,485 ÷ 3 = 893,161.6667
If the quotient is a whole number, then 3 and 893,161.6667 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 | 2,679,485 | |
| -1 | -2,679,485 |
Let's try dividing by 4:
2,679,485 ÷ 4 = 669,871.25
If the quotient is a whole number, then 4 and 669,871.25 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 | 2,679,485 | |
| -1 | 2,679,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 59 | 155 | 293 | 295 | 1,465 | 1,829 | 9,083 | 9,145 | 17,287 | 45,415 | 86,435 | 535,897 | 2,679,485 |
| -1 | -5 | -31 | -59 | -155 | -293 | -295 | -1,465 | -1,829 | -9,083 | -9,145 | -17,287 | -45,415 | -86,435 | -535,897 | -2,679,485 |
