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 25,176,095, 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 | 25,176,095 | |
| -1 | -25,176,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,176,095.
Example:
1 x 25,176,095 = 25,176,095
and
-1 x -25,176,095 = 25,176,095
Notice both answers equal 25,176,095
With that explanation out of the way, let's continue. Next, we take the number 25,176,095 and divide it by 2:
25,176,095 ÷ 2 = 12,588,047.5
If the quotient is a whole number, then 2 and 12,588,047.5 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 | 25,176,095 | |
| -1 | -25,176,095 |
Now, we try dividing 25,176,095 by 3:
25,176,095 ÷ 3 = 8,392,031.6667
If the quotient is a whole number, then 3 and 8,392,031.6667 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 | 25,176,095 | |
| -1 | -25,176,095 |
Let's try dividing by 4:
25,176,095 ÷ 4 = 6,294,023.75
If the quotient is a whole number, then 4 and 6,294,023.75 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 | 25,176,095 | |
| -1 | 25,176,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 185 | 259 | 1,295 | 19,441 | 97,205 | 136,087 | 680,435 | 719,317 | 3,596,585 | 5,035,219 | 25,176,095 |
| -1 | -5 | -7 | -35 | -37 | -185 | -259 | -1,295 | -19,441 | -97,205 | -136,087 | -680,435 | -719,317 | -3,596,585 | -5,035,219 | -25,176,095 |
