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 26,053,445, 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 | 26,053,445 | |
| -1 | -26,053,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,053,445.
Example:
1 x 26,053,445 = 26,053,445
and
-1 x -26,053,445 = 26,053,445
Notice both answers equal 26,053,445
With that explanation out of the way, let's continue. Next, we take the number 26,053,445 and divide it by 2:
26,053,445 ÷ 2 = 13,026,722.5
If the quotient is a whole number, then 2 and 13,026,722.5 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 | 26,053,445 | |
| -1 | -26,053,445 |
Now, we try dividing 26,053,445 by 3:
26,053,445 ÷ 3 = 8,684,481.6667
If the quotient is a whole number, then 3 and 8,684,481.6667 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 | 26,053,445 | |
| -1 | -26,053,445 |
Let's try dividing by 4:
26,053,445 ÷ 4 = 6,513,361.25
If the quotient is a whole number, then 4 and 6,513,361.25 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 | 26,053,445 | |
| -1 | 26,053,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 641 | 739 | 3,205 | 3,695 | 7,051 | 8,129 | 35,255 | 40,645 | 473,699 | 2,368,495 | 5,210,689 | 26,053,445 |
| -1 | -5 | -11 | -55 | -641 | -739 | -3,205 | -3,695 | -7,051 | -8,129 | -35,255 | -40,645 | -473,699 | -2,368,495 | -5,210,689 | -26,053,445 |
