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 127,156,531, 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 | 127,156,531 | |
| -1 | -127,156,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 127,156,531.
Example:
1 x 127,156,531 = 127,156,531
and
-1 x -127,156,531 = 127,156,531
Notice both answers equal 127,156,531
With that explanation out of the way, let's continue. Next, we take the number 127,156,531 and divide it by 2:
127,156,531 ÷ 2 = 63,578,265.5
If the quotient is a whole number, then 2 and 63,578,265.5 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 | 127,156,531 | |
| -1 | -127,156,531 |
Now, we try dividing 127,156,531 by 3:
127,156,531 ÷ 3 = 42,385,510.3333
If the quotient is a whole number, then 3 and 42,385,510.3333 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 | 127,156,531 | |
| -1 | -127,156,531 |
Let's try dividing by 4:
127,156,531 ÷ 4 = 31,789,132.75
If the quotient is a whole number, then 4 and 31,789,132.75 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 | 127,156,531 | |
| -1 | 127,156,531 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 191 | 703 | 947 | 3,629 | 7,067 | 17,993 | 35,039 | 134,273 | 180,877 | 665,741 | 3,436,663 | 6,692,449 | 127,156,531 |
| -1 | -19 | -37 | -191 | -703 | -947 | -3,629 | -7,067 | -17,993 | -35,039 | -134,273 | -180,877 | -665,741 | -3,436,663 | -6,692,449 | -127,156,531 |
