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 189,582,367, 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 | 189,582,367 | |
| -1 | -189,582,367 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 189,582,367.
Example:
1 x 189,582,367 = 189,582,367
and
-1 x -189,582,367 = 189,582,367
Notice both answers equal 189,582,367
With that explanation out of the way, let's continue. Next, we take the number 189,582,367 and divide it by 2:
189,582,367 ÷ 2 = 94,791,183.5
If the quotient is a whole number, then 2 and 94,791,183.5 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 | 189,582,367 | |
| -1 | -189,582,367 |
Now, we try dividing 189,582,367 by 3:
189,582,367 ÷ 3 = 63,194,122.3333
If the quotient is a whole number, then 3 and 63,194,122.3333 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 | 189,582,367 | |
| -1 | -189,582,367 |
Let's try dividing by 4:
189,582,367 ÷ 4 = 47,395,591.75
If the quotient is a whole number, then 4 and 47,395,591.75 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 | 189,582,367 | |
| -1 | 189,582,367 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 157 | 377 | 2,041 | 3,203 | 4,553 | 41,639 | 59,189 | 92,887 | 502,871 | 1,207,531 | 6,537,323 | 14,583,259 | 189,582,367 |
| -1 | -13 | -29 | -157 | -377 | -2,041 | -3,203 | -4,553 | -41,639 | -59,189 | -92,887 | -502,871 | -1,207,531 | -6,537,323 | -14,583,259 | -189,582,367 |
