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 10,319,617, 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 | 10,319,617 | |
| -1 | -10,319,617 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,319,617.
Example:
1 x 10,319,617 = 10,319,617
and
-1 x -10,319,617 = 10,319,617
Notice both answers equal 10,319,617
With that explanation out of the way, let's continue. Next, we take the number 10,319,617 and divide it by 2:
10,319,617 ÷ 2 = 5,159,808.5
If the quotient is a whole number, then 2 and 5,159,808.5 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 | 10,319,617 | |
| -1 | -10,319,617 |
Now, we try dividing 10,319,617 by 3:
10,319,617 ÷ 3 = 3,439,872.3333
If the quotient is a whole number, then 3 and 3,439,872.3333 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 | 10,319,617 | |
| -1 | -10,319,617 |
Let's try dividing by 4:
10,319,617 ÷ 4 = 2,579,904.25
If the quotient is a whole number, then 4 and 2,579,904.25 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 | 10,319,617 | |
| -1 | 10,319,617 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 77 | 161 | 253 | 1,771 | 5,827 | 40,789 | 64,097 | 134,021 | 448,679 | 938,147 | 1,474,231 | 10,319,617 |
| -1 | -7 | -11 | -23 | -77 | -161 | -253 | -1,771 | -5,827 | -40,789 | -64,097 | -134,021 | -448,679 | -938,147 | -1,474,231 | -10,319,617 |
