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 26,210,653, 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 | 26,210,653 | |
| -1 | -26,210,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,210,653.
Example:
1 x 26,210,653 = 26,210,653
and
-1 x -26,210,653 = 26,210,653
Notice both answers equal 26,210,653
With that explanation out of the way, let's continue. Next, we take the number 26,210,653 and divide it by 2:
26,210,653 ÷ 2 = 13,105,326.5
If the quotient is a whole number, then 2 and 13,105,326.5 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 | 26,210,653 | |
| -1 | -26,210,653 |
Now, we try dividing 26,210,653 by 3:
26,210,653 ÷ 3 = 8,736,884.3333
If the quotient is a whole number, then 3 and 8,736,884.3333 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 | 26,210,653 | |
| -1 | -26,210,653 |
Let's try dividing by 4:
26,210,653 ÷ 4 = 6,552,663.25
If the quotient is a whole number, then 4 and 6,552,663.25 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 | 26,210,653 | |
| -1 | 26,210,653 |
If you did it right, you will end up with this table:
| 1 | 7 | 83 | 197 | 229 | 581 | 1,379 | 1,603 | 16,351 | 19,007 | 45,113 | 114,457 | 133,049 | 315,791 | 3,744,379 | 26,210,653 |
| -1 | -7 | -83 | -197 | -229 | -581 | -1,379 | -1,603 | -16,351 | -19,007 | -45,113 | -114,457 | -133,049 | -315,791 | -3,744,379 | -26,210,653 |
