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 26,210,723, 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 | 26,210,723 | |
| -1 | -26,210,723 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,210,723.
Example:
1 x 26,210,723 = 26,210,723
and
-1 x -26,210,723 = 26,210,723
Notice both answers equal 26,210,723
With that explanation out of the way, let's continue. Next, we take the number 26,210,723 and divide it by 2:
26,210,723 ÷ 2 = 13,105,361.5
If the quotient is a whole number, then 2 and 13,105,361.5 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 | 26,210,723 | |
| -1 | -26,210,723 |
Now, we try dividing 26,210,723 by 3:
26,210,723 ÷ 3 = 8,736,907.6667
If the quotient is a whole number, then 3 and 8,736,907.6667 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 | 26,210,723 | |
| -1 | -26,210,723 |
Let's try dividing by 4:
26,210,723 ÷ 4 = 6,552,680.75
If the quotient is a whole number, then 4 and 6,552,680.75 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 | 26,210,723 | |
| -1 | 26,210,723 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 73 | 77 | 511 | 803 | 4,663 | 5,621 | 32,641 | 51,293 | 340,399 | 359,051 | 2,382,793 | 3,744,389 | 26,210,723 |
| -1 | -7 | -11 | -73 | -77 | -511 | -803 | -4,663 | -5,621 | -32,641 | -51,293 | -340,399 | -359,051 | -2,382,793 | -3,744,389 | -26,210,723 |
