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 26,742,163, 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 | 26,742,163 | |
| -1 | -26,742,163 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,742,163.
Example:
1 x 26,742,163 = 26,742,163
and
-1 x -26,742,163 = 26,742,163
Notice both answers equal 26,742,163
With that explanation out of the way, let's continue. Next, we take the number 26,742,163 and divide it by 2:
26,742,163 ÷ 2 = 13,371,081.5
If the quotient is a whole number, then 2 and 13,371,081.5 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 | 26,742,163 | |
| -1 | -26,742,163 |
Now, we try dividing 26,742,163 by 3:
26,742,163 ÷ 3 = 8,914,054.3333
If the quotient is a whole number, then 3 and 8,914,054.3333 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 | 26,742,163 | |
| -1 | -26,742,163 |
Let's try dividing by 4:
26,742,163 ÷ 4 = 6,685,540.75
If the quotient is a whole number, then 4 and 6,685,540.75 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 | 26,742,163 | |
| -1 | 26,742,163 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 73 | 413 | 511 | 887 | 4,307 | 6,209 | 30,149 | 52,333 | 64,751 | 366,331 | 453,257 | 3,820,309 | 26,742,163 |
| -1 | -7 | -59 | -73 | -413 | -511 | -887 | -4,307 | -6,209 | -30,149 | -52,333 | -64,751 | -366,331 | -453,257 | -3,820,309 | -26,742,163 |
