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 26,546,165, 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 | 26,546,165 | |
| -1 | -26,546,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,546,165.
Example:
1 x 26,546,165 = 26,546,165
and
-1 x -26,546,165 = 26,546,165
Notice both answers equal 26,546,165
With that explanation out of the way, let's continue. Next, we take the number 26,546,165 and divide it by 2:
26,546,165 ÷ 2 = 13,273,082.5
If the quotient is a whole number, then 2 and 13,273,082.5 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 | 26,546,165 | |
| -1 | -26,546,165 |
Now, we try dividing 26,546,165 by 3:
26,546,165 ÷ 3 = 8,848,721.6667
If the quotient is a whole number, then 3 and 8,848,721.6667 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 | 26,546,165 | |
| -1 | -26,546,165 |
Let's try dividing by 4:
26,546,165 ÷ 4 = 6,636,541.25
If the quotient is a whole number, then 4 and 6,636,541.25 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 | 26,546,165 | |
| -1 | 26,546,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 59 | 107 | 145 | 295 | 535 | 841 | 1,711 | 3,103 | 4,205 | 6,313 | 8,555 | 15,515 | 31,565 | 49,619 | 89,987 | 183,077 | 248,095 | 449,935 | 915,385 | 5,309,233 | 26,546,165 |
| -1 | -5 | -29 | -59 | -107 | -145 | -295 | -535 | -841 | -1,711 | -3,103 | -4,205 | -6,313 | -8,555 | -15,515 | -31,565 | -49,619 | -89,987 | -183,077 | -248,095 | -449,935 | -915,385 | -5,309,233 | -26,546,165 |
