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 25,314,355, 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 | 25,314,355 | |
| -1 | -25,314,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,314,355.
Example:
1 x 25,314,355 = 25,314,355
and
-1 x -25,314,355 = 25,314,355
Notice both answers equal 25,314,355
With that explanation out of the way, let's continue. Next, we take the number 25,314,355 and divide it by 2:
25,314,355 ÷ 2 = 12,657,177.5
If the quotient is a whole number, then 2 and 12,657,177.5 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 | 25,314,355 | |
| -1 | -25,314,355 |
Now, we try dividing 25,314,355 by 3:
25,314,355 ÷ 3 = 8,438,118.3333
If the quotient is a whole number, then 3 and 8,438,118.3333 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 | 25,314,355 | |
| -1 | -25,314,355 |
Let's try dividing by 4:
25,314,355 ÷ 4 = 6,328,588.75
If the quotient is a whole number, then 4 and 6,328,588.75 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 | 25,314,355 | |
| -1 | 25,314,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 149 | 745 | 1,639 | 3,089 | 8,195 | 15,445 | 33,979 | 169,895 | 460,261 | 2,301,305 | 5,062,871 | 25,314,355 |
| -1 | -5 | -11 | -55 | -149 | -745 | -1,639 | -3,089 | -8,195 | -15,445 | -33,979 | -169,895 | -460,261 | -2,301,305 | -5,062,871 | -25,314,355 |
