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 6,715,379, 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 | 6,715,379 | |
| -1 | -6,715,379 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,715,379.
Example:
1 x 6,715,379 = 6,715,379
and
-1 x -6,715,379 = 6,715,379
Notice both answers equal 6,715,379
With that explanation out of the way, let's continue. Next, we take the number 6,715,379 and divide it by 2:
6,715,379 ÷ 2 = 3,357,689.5
If the quotient is a whole number, then 2 and 3,357,689.5 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 | 6,715,379 | |
| -1 | -6,715,379 |
Now, we try dividing 6,715,379 by 3:
6,715,379 ÷ 3 = 2,238,459.6667
If the quotient is a whole number, then 3 and 2,238,459.6667 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 | 6,715,379 | |
| -1 | -6,715,379 |
Let's try dividing by 4:
6,715,379 ÷ 4 = 1,678,844.75
If the quotient is a whole number, then 4 and 1,678,844.75 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 | 6,715,379 | |
| -1 | 6,715,379 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 23 | 121 | 127 | 209 | 253 | 437 | 1,397 | 2,299 | 2,413 | 2,783 | 2,921 | 4,807 | 15,367 | 26,543 | 32,131 | 52,877 | 55,499 | 291,973 | 353,441 | 610,489 | 6,715,379 |
| -1 | -11 | -19 | -23 | -121 | -127 | -209 | -253 | -437 | -1,397 | -2,299 | -2,413 | -2,783 | -2,921 | -4,807 | -15,367 | -26,543 | -32,131 | -52,877 | -55,499 | -291,973 | -353,441 | -610,489 | -6,715,379 |
