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 26,650,477, 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 | 26,650,477 | |
| -1 | -26,650,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,650,477.
Example:
1 x 26,650,477 = 26,650,477
and
-1 x -26,650,477 = 26,650,477
Notice both answers equal 26,650,477
With that explanation out of the way, let's continue. Next, we take the number 26,650,477 and divide it by 2:
26,650,477 ÷ 2 = 13,325,238.5
If the quotient is a whole number, then 2 and 13,325,238.5 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 | 26,650,477 | |
| -1 | -26,650,477 |
Now, we try dividing 26,650,477 by 3:
26,650,477 ÷ 3 = 8,883,492.3333
If the quotient is a whole number, then 3 and 8,883,492.3333 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 | 26,650,477 | |
| -1 | -26,650,477 |
Let's try dividing by 4:
26,650,477 ÷ 4 = 6,662,619.25
If the quotient is a whole number, then 4 and 6,662,619.25 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 | 26,650,477 | |
| -1 | 26,650,477 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 173 | 373 | 413 | 1,211 | 2,611 | 10,207 | 22,007 | 64,529 | 71,449 | 154,049 | 451,703 | 3,807,211 | 26,650,477 |
| -1 | -7 | -59 | -173 | -373 | -413 | -1,211 | -2,611 | -10,207 | -22,007 | -64,529 | -71,449 | -154,049 | -451,703 | -3,807,211 | -26,650,477 |
