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 152,377,127, 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 | 152,377,127 | |
| -1 | -152,377,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,377,127.
Example:
1 x 152,377,127 = 152,377,127
and
-1 x -152,377,127 = 152,377,127
Notice both answers equal 152,377,127
With that explanation out of the way, let's continue. Next, we take the number 152,377,127 and divide it by 2:
152,377,127 ÷ 2 = 76,188,563.5
If the quotient is a whole number, then 2 and 76,188,563.5 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 | 152,377,127 | |
| -1 | -152,377,127 |
Now, we try dividing 152,377,127 by 3:
152,377,127 ÷ 3 = 50,792,375.6667
If the quotient is a whole number, then 3 and 50,792,375.6667 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 | 152,377,127 | |
| -1 | -152,377,127 |
Let's try dividing by 4:
152,377,127 ÷ 4 = 38,094,281.75
If the quotient is a whole number, then 4 and 38,094,281.75 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 | 152,377,127 | |
| -1 | 152,377,127 |
If you did it right, you will end up with this table:
| 1 | 7 | 83 | 163 | 581 | 1,141 | 1,609 | 11,263 | 13,529 | 94,703 | 133,547 | 262,267 | 934,829 | 1,835,869 | 21,768,161 | 152,377,127 |
| -1 | -7 | -83 | -163 | -581 | -1,141 | -1,609 | -11,263 | -13,529 | -94,703 | -133,547 | -262,267 | -934,829 | -1,835,869 | -21,768,161 | -152,377,127 |
