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 178,130,095, 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 | 178,130,095 | |
| -1 | -178,130,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 178,130,095.
Example:
1 x 178,130,095 = 178,130,095
and
-1 x -178,130,095 = 178,130,095
Notice both answers equal 178,130,095
With that explanation out of the way, let's continue. Next, we take the number 178,130,095 and divide it by 2:
178,130,095 ÷ 2 = 89,065,047.5
If the quotient is a whole number, then 2 and 89,065,047.5 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 | 178,130,095 | |
| -1 | -178,130,095 |
Now, we try dividing 178,130,095 by 3:
178,130,095 ÷ 3 = 59,376,698.3333
If the quotient is a whole number, then 3 and 59,376,698.3333 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 | 178,130,095 | |
| -1 | -178,130,095 |
Let's try dividing by 4:
178,130,095 ÷ 4 = 44,532,523.75
If the quotient is a whole number, then 4 and 44,532,523.75 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 | 178,130,095 | |
| -1 | 178,130,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 249,133 | 1,245,665 | 2,740,463 | 3,238,729 | 13,702,315 | 16,193,645 | 35,626,019 | 178,130,095 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -249,133 | -1,245,665 | -2,740,463 | -3,238,729 | -13,702,315 | -16,193,645 | -35,626,019 | -178,130,095 |
