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 26,151,505, 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 | 26,151,505 | |
| -1 | -26,151,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,151,505.
Example:
1 x 26,151,505 = 26,151,505
and
-1 x -26,151,505 = 26,151,505
Notice both answers equal 26,151,505
With that explanation out of the way, let's continue. Next, we take the number 26,151,505 and divide it by 2:
26,151,505 ÷ 2 = 13,075,752.5
If the quotient is a whole number, then 2 and 13,075,752.5 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 | 26,151,505 | |
| -1 | -26,151,505 |
Now, we try dividing 26,151,505 by 3:
26,151,505 ÷ 3 = 8,717,168.3333
If the quotient is a whole number, then 3 and 8,717,168.3333 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 | 26,151,505 | |
| -1 | -26,151,505 |
Let's try dividing by 4:
26,151,505 ÷ 4 = 6,537,876.25
If the quotient is a whole number, then 4 and 6,537,876.25 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 | 26,151,505 | |
| -1 | 26,151,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 47 | 95 | 235 | 893 | 4,465 | 5,857 | 29,285 | 111,283 | 275,279 | 556,415 | 1,376,395 | 5,230,301 | 26,151,505 |
| -1 | -5 | -19 | -47 | -95 | -235 | -893 | -4,465 | -5,857 | -29,285 | -111,283 | -275,279 | -556,415 | -1,376,395 | -5,230,301 | -26,151,505 |
