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 6,970,615, 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 | 6,970,615 | |
| -1 | -6,970,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,970,615.
Example:
1 x 6,970,615 = 6,970,615
and
-1 x -6,970,615 = 6,970,615
Notice both answers equal 6,970,615
With that explanation out of the way, let's continue. Next, we take the number 6,970,615 and divide it by 2:
6,970,615 ÷ 2 = 3,485,307.5
If the quotient is a whole number, then 2 and 3,485,307.5 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 | 6,970,615 | |
| -1 | -6,970,615 |
Now, we try dividing 6,970,615 by 3:
6,970,615 ÷ 3 = 2,323,538.3333
If the quotient is a whole number, then 3 and 2,323,538.3333 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 | 6,970,615 | |
| -1 | -6,970,615 |
Let's try dividing by 4:
6,970,615 ÷ 4 = 1,742,653.75
If the quotient is a whole number, then 4 and 1,742,653.75 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 | 6,970,615 | |
| -1 | 6,970,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 41 | 185 | 205 | 919 | 1,517 | 4,595 | 7,585 | 34,003 | 37,679 | 170,015 | 188,395 | 1,394,123 | 6,970,615 |
| -1 | -5 | -37 | -41 | -185 | -205 | -919 | -1,517 | -4,595 | -7,585 | -34,003 | -37,679 | -170,015 | -188,395 | -1,394,123 | -6,970,615 |
