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 6,470,597, 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 | 6,470,597 | |
| -1 | -6,470,597 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,470,597.
Example:
1 x 6,470,597 = 6,470,597
and
-1 x -6,470,597 = 6,470,597
Notice both answers equal 6,470,597
With that explanation out of the way, let's continue. Next, we take the number 6,470,597 and divide it by 2:
6,470,597 ÷ 2 = 3,235,298.5
If the quotient is a whole number, then 2 and 3,235,298.5 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 | 6,470,597 | |
| -1 | -6,470,597 |
Now, we try dividing 6,470,597 by 3:
6,470,597 ÷ 3 = 2,156,865.6667
If the quotient is a whole number, then 3 and 2,156,865.6667 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 | 6,470,597 | |
| -1 | -6,470,597 |
Let's try dividing by 4:
6,470,597 ÷ 4 = 1,617,649.25
If the quotient is a whole number, then 4 and 1,617,649.25 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 | 6,470,597 | |
| -1 | 6,470,597 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 43 | 49 | 83 | 259 | 301 | 581 | 1,591 | 1,813 | 2,107 | 3,071 | 3,569 | 4,067 | 11,137 | 21,497 | 24,983 | 77,959 | 132,053 | 150,479 | 174,881 | 924,371 | 6,470,597 |
| -1 | -7 | -37 | -43 | -49 | -83 | -259 | -301 | -581 | -1,591 | -1,813 | -2,107 | -3,071 | -3,569 | -4,067 | -11,137 | -21,497 | -24,983 | -77,959 | -132,053 | -150,479 | -174,881 | -924,371 | -6,470,597 |
