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 26,176,555, 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 | 26,176,555 | |
| -1 | -26,176,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,176,555.
Example:
1 x 26,176,555 = 26,176,555
and
-1 x -26,176,555 = 26,176,555
Notice both answers equal 26,176,555
With that explanation out of the way, let's continue. Next, we take the number 26,176,555 and divide it by 2:
26,176,555 ÷ 2 = 13,088,277.5
If the quotient is a whole number, then 2 and 13,088,277.5 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 | 26,176,555 | |
| -1 | -26,176,555 |
Now, we try dividing 26,176,555 by 3:
26,176,555 ÷ 3 = 8,725,518.3333
If the quotient is a whole number, then 3 and 8,725,518.3333 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 | 26,176,555 | |
| -1 | -26,176,555 |
Let's try dividing by 4:
26,176,555 ÷ 4 = 6,544,138.75
If the quotient is a whole number, then 4 and 6,544,138.75 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 | 26,176,555 | |
| -1 | 26,176,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 281 | 601 | 1,405 | 3,005 | 8,711 | 18,631 | 43,555 | 93,155 | 168,881 | 844,405 | 5,235,311 | 26,176,555 |
| -1 | -5 | -31 | -155 | -281 | -601 | -1,405 | -3,005 | -8,711 | -18,631 | -43,555 | -93,155 | -168,881 | -844,405 | -5,235,311 | -26,176,555 |
