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 26,451,235, 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 | 26,451,235 | |
| -1 | -26,451,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,451,235.
Example:
1 x 26,451,235 = 26,451,235
and
-1 x -26,451,235 = 26,451,235
Notice both answers equal 26,451,235
With that explanation out of the way, let's continue. Next, we take the number 26,451,235 and divide it by 2:
26,451,235 ÷ 2 = 13,225,617.5
If the quotient is a whole number, then 2 and 13,225,617.5 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 | 26,451,235 | |
| -1 | -26,451,235 |
Now, we try dividing 26,451,235 by 3:
26,451,235 ÷ 3 = 8,817,078.3333
If the quotient is a whole number, then 3 and 8,817,078.3333 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 | 26,451,235 | |
| -1 | -26,451,235 |
Let's try dividing by 4:
26,451,235 ÷ 4 = 6,612,808.75
If the quotient is a whole number, then 4 and 6,612,808.75 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 | 26,451,235 | |
| -1 | 26,451,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 85 | 215 | 731 | 3,655 | 7,237 | 36,185 | 123,029 | 311,191 | 615,145 | 1,555,955 | 5,290,247 | 26,451,235 |
| -1 | -5 | -17 | -43 | -85 | -215 | -731 | -3,655 | -7,237 | -36,185 | -123,029 | -311,191 | -615,145 | -1,555,955 | -5,290,247 | -26,451,235 |
