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 6,479,515, 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 | 6,479,515 | |
| -1 | -6,479,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,479,515.
Example:
1 x 6,479,515 = 6,479,515
and
-1 x -6,479,515 = 6,479,515
Notice both answers equal 6,479,515
With that explanation out of the way, let's continue. Next, we take the number 6,479,515 and divide it by 2:
6,479,515 ÷ 2 = 3,239,757.5
If the quotient is a whole number, then 2 and 3,239,757.5 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 | 6,479,515 | |
| -1 | -6,479,515 |
Now, we try dividing 6,479,515 by 3:
6,479,515 ÷ 3 = 2,159,838.3333
If the quotient is a whole number, then 3 and 2,159,838.3333 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 | 6,479,515 | |
| -1 | -6,479,515 |
Let's try dividing by 4:
6,479,515 ÷ 4 = 1,619,878.75
If the quotient is a whole number, then 4 and 1,619,878.75 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 | 6,479,515 | |
| -1 | 6,479,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 53 | 245 | 265 | 371 | 499 | 1,855 | 2,495 | 2,597 | 3,493 | 12,985 | 17,465 | 24,451 | 26,447 | 122,255 | 132,235 | 185,129 | 925,645 | 1,295,903 | 6,479,515 |
| -1 | -5 | -7 | -35 | -49 | -53 | -245 | -265 | -371 | -499 | -1,855 | -2,495 | -2,597 | -3,493 | -12,985 | -17,465 | -24,451 | -26,447 | -122,255 | -132,235 | -185,129 | -925,645 | -1,295,903 | -6,479,515 |
