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 26,573,723, 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 | 26,573,723 | |
| -1 | -26,573,723 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,573,723.
Example:
1 x 26,573,723 = 26,573,723
and
-1 x -26,573,723 = 26,573,723
Notice both answers equal 26,573,723
With that explanation out of the way, let's continue. Next, we take the number 26,573,723 and divide it by 2:
26,573,723 ÷ 2 = 13,286,861.5
If the quotient is a whole number, then 2 and 13,286,861.5 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 | 26,573,723 | |
| -1 | -26,573,723 |
Now, we try dividing 26,573,723 by 3:
26,573,723 ÷ 3 = 8,857,907.6667
If the quotient is a whole number, then 3 and 8,857,907.6667 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 | 26,573,723 | |
| -1 | -26,573,723 |
Let's try dividing by 4:
26,573,723 ÷ 4 = 6,643,430.75
If the quotient is a whole number, then 4 and 6,643,430.75 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 | 26,573,723 | |
| -1 | 26,573,723 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 53 | 209 | 583 | 1,007 | 2,399 | 11,077 | 26,389 | 45,581 | 127,147 | 501,391 | 1,398,617 | 2,415,793 | 26,573,723 |
| -1 | -11 | -19 | -53 | -209 | -583 | -1,007 | -2,399 | -11,077 | -26,389 | -45,581 | -127,147 | -501,391 | -1,398,617 | -2,415,793 | -26,573,723 |
