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 158,883,215, 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 | 158,883,215 | |
| -1 | -158,883,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 158,883,215.
Example:
1 x 158,883,215 = 158,883,215
and
-1 x -158,883,215 = 158,883,215
Notice both answers equal 158,883,215
With that explanation out of the way, let's continue. Next, we take the number 158,883,215 and divide it by 2:
158,883,215 ÷ 2 = 79,441,607.5
If the quotient is a whole number, then 2 and 79,441,607.5 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 | 158,883,215 | |
| -1 | -158,883,215 |
Now, we try dividing 158,883,215 by 3:
158,883,215 ÷ 3 = 52,961,071.6667
If the quotient is a whole number, then 3 and 52,961,071.6667 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 | 158,883,215 | |
| -1 | -158,883,215 |
Let's try dividing by 4:
158,883,215 ÷ 4 = 39,720,803.75
If the quotient is a whole number, then 4 and 39,720,803.75 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 | 158,883,215 | |
| -1 | 158,883,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 157 | 785 | 4,867 | 6,529 | 24,335 | 32,645 | 202,399 | 1,011,995 | 1,025,053 | 5,125,265 | 31,776,643 | 158,883,215 |
| -1 | -5 | -31 | -155 | -157 | -785 | -4,867 | -6,529 | -24,335 | -32,645 | -202,399 | -1,011,995 | -1,025,053 | -5,125,265 | -31,776,643 | -158,883,215 |
