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 6,743,815, 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 | 6,743,815 | |
| -1 | -6,743,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,743,815.
Example:
1 x 6,743,815 = 6,743,815
and
-1 x -6,743,815 = 6,743,815
Notice both answers equal 6,743,815
With that explanation out of the way, let's continue. Next, we take the number 6,743,815 and divide it by 2:
6,743,815 ÷ 2 = 3,371,907.5
If the quotient is a whole number, then 2 and 3,371,907.5 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 | 6,743,815 | |
| -1 | -6,743,815 |
Now, we try dividing 6,743,815 by 3:
6,743,815 ÷ 3 = 2,247,938.3333
If the quotient is a whole number, then 3 and 2,247,938.3333 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 | 6,743,815 | |
| -1 | -6,743,815 |
Let's try dividing by 4:
6,743,815 ÷ 4 = 1,685,953.75
If the quotient is a whole number, then 4 and 1,685,953.75 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 | 6,743,815 | |
| -1 | 6,743,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 289 | 359 | 1,105 | 1,445 | 1,795 | 3,757 | 4,667 | 6,103 | 18,785 | 23,335 | 30,515 | 79,339 | 103,751 | 396,695 | 518,755 | 1,348,763 | 6,743,815 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -289 | -359 | -1,105 | -1,445 | -1,795 | -3,757 | -4,667 | -6,103 | -18,785 | -23,335 | -30,515 | -79,339 | -103,751 | -396,695 | -518,755 | -1,348,763 | -6,743,815 |
