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 26,265,151, 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 | 26,265,151 | |
| -1 | -26,265,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,265,151.
Example:
1 x 26,265,151 = 26,265,151
and
-1 x -26,265,151 = 26,265,151
Notice both answers equal 26,265,151
With that explanation out of the way, let's continue. Next, we take the number 26,265,151 and divide it by 2:
26,265,151 ÷ 2 = 13,132,575.5
If the quotient is a whole number, then 2 and 13,132,575.5 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 | 26,265,151 | |
| -1 | -26,265,151 |
Now, we try dividing 26,265,151 by 3:
26,265,151 ÷ 3 = 8,755,050.3333
If the quotient is a whole number, then 3 and 8,755,050.3333 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 | 26,265,151 | |
| -1 | -26,265,151 |
Let's try dividing by 4:
26,265,151 ÷ 4 = 6,566,287.75
If the quotient is a whole number, then 4 and 6,566,287.75 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 | 26,265,151 | |
| -1 | 26,265,151 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 101 | 503 | 517 | 1,111 | 4,747 | 5,533 | 23,641 | 50,803 | 52,217 | 260,051 | 558,833 | 2,387,741 | 26,265,151 |
| -1 | -11 | -47 | -101 | -503 | -517 | -1,111 | -4,747 | -5,533 | -23,641 | -50,803 | -52,217 | -260,051 | -558,833 | -2,387,741 | -26,265,151 |
