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 26,953,945, 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 | 26,953,945 | |
| -1 | -26,953,945 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,953,945.
Example:
1 x 26,953,945 = 26,953,945
and
-1 x -26,953,945 = 26,953,945
Notice both answers equal 26,953,945
With that explanation out of the way, let's continue. Next, we take the number 26,953,945 and divide it by 2:
26,953,945 ÷ 2 = 13,476,972.5
If the quotient is a whole number, then 2 and 13,476,972.5 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 | 26,953,945 | |
| -1 | -26,953,945 |
Now, we try dividing 26,953,945 by 3:
26,953,945 ÷ 3 = 8,984,648.3333
If the quotient is a whole number, then 3 and 8,984,648.3333 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 | 26,953,945 | |
| -1 | -26,953,945 |
Let's try dividing by 4:
26,953,945 ÷ 4 = 6,738,486.25
If the quotient is a whole number, then 4 and 6,738,486.25 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 | 26,953,945 | |
| -1 | 26,953,945 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 53 | 185 | 265 | 1,961 | 2,749 | 9,805 | 13,745 | 101,713 | 145,697 | 508,565 | 728,485 | 5,390,789 | 26,953,945 |
| -1 | -5 | -37 | -53 | -185 | -265 | -1,961 | -2,749 | -9,805 | -13,745 | -101,713 | -145,697 | -508,565 | -728,485 | -5,390,789 | -26,953,945 |
