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 26,273,105, 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 | 26,273,105 | |
| -1 | -26,273,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,273,105.
Example:
1 x 26,273,105 = 26,273,105
and
-1 x -26,273,105 = 26,273,105
Notice both answers equal 26,273,105
With that explanation out of the way, let's continue. Next, we take the number 26,273,105 and divide it by 2:
26,273,105 ÷ 2 = 13,136,552.5
If the quotient is a whole number, then 2 and 13,136,552.5 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 | 26,273,105 | |
| -1 | -26,273,105 |
Now, we try dividing 26,273,105 by 3:
26,273,105 ÷ 3 = 8,757,701.6667
If the quotient is a whole number, then 3 and 8,757,701.6667 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 | 26,273,105 | |
| -1 | -26,273,105 |
Let's try dividing by 4:
26,273,105 ÷ 4 = 6,568,276.25
If the quotient is a whole number, then 4 and 6,568,276.25 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 | 26,273,105 | |
| -1 | 26,273,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 347 | 797 | 1,735 | 3,985 | 6,593 | 15,143 | 32,965 | 75,715 | 276,559 | 1,382,795 | 5,254,621 | 26,273,105 |
| -1 | -5 | -19 | -95 | -347 | -797 | -1,735 | -3,985 | -6,593 | -15,143 | -32,965 | -75,715 | -276,559 | -1,382,795 | -5,254,621 | -26,273,105 |
