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 120,157,063, 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 | 120,157,063 | |
| -1 | -120,157,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,157,063.
Example:
1 x 120,157,063 = 120,157,063
and
-1 x -120,157,063 = 120,157,063
Notice both answers equal 120,157,063
With that explanation out of the way, let's continue. Next, we take the number 120,157,063 and divide it by 2:
120,157,063 ÷ 2 = 60,078,531.5
If the quotient is a whole number, then 2 and 60,078,531.5 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 | 120,157,063 | |
| -1 | -120,157,063 |
Now, we try dividing 120,157,063 by 3:
120,157,063 ÷ 3 = 40,052,354.3333
If the quotient is a whole number, then 3 and 40,052,354.3333 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 | 120,157,063 | |
| -1 | -120,157,063 |
Let's try dividing by 4:
120,157,063 ÷ 4 = 30,039,265.75
If the quotient is a whole number, then 4 and 30,039,265.75 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 | 120,157,063 | |
| -1 | 120,157,063 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 67 | 71 | 377 | 871 | 923 | 1,943 | 2,059 | 4,489 | 4,757 | 25,259 | 26,767 | 58,357 | 61,841 | 130,181 | 137,953 | 318,719 | 1,692,353 | 1,793,389 | 4,143,347 | 9,242,851 | 120,157,063 |
| -1 | -13 | -29 | -67 | -71 | -377 | -871 | -923 | -1,943 | -2,059 | -4,489 | -4,757 | -25,259 | -26,767 | -58,357 | -61,841 | -130,181 | -137,953 | -318,719 | -1,692,353 | -1,793,389 | -4,143,347 | -9,242,851 | -120,157,063 |
