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 131,424,035, 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 | 131,424,035 | |
| -1 | -131,424,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 131,424,035.
Example:
1 x 131,424,035 = 131,424,035
and
-1 x -131,424,035 = 131,424,035
Notice both answers equal 131,424,035
With that explanation out of the way, let's continue. Next, we take the number 131,424,035 and divide it by 2:
131,424,035 ÷ 2 = 65,712,017.5
If the quotient is a whole number, then 2 and 65,712,017.5 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 | 131,424,035 | |
| -1 | -131,424,035 |
Now, we try dividing 131,424,035 by 3:
131,424,035 ÷ 3 = 43,808,011.6667
If the quotient is a whole number, then 3 and 43,808,011.6667 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 | 131,424,035 | |
| -1 | -131,424,035 |
Let's try dividing by 4:
131,424,035 ÷ 4 = 32,856,008.75
If the quotient is a whole number, then 4 and 32,856,008.75 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 | 131,424,035 | |
| -1 | 131,424,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 277 | 1,385 | 3,061 | 8,587 | 15,305 | 42,935 | 94,891 | 474,455 | 847,897 | 4,239,485 | 26,284,807 | 131,424,035 |
| -1 | -5 | -31 | -155 | -277 | -1,385 | -3,061 | -8,587 | -15,305 | -42,935 | -94,891 | -474,455 | -847,897 | -4,239,485 | -26,284,807 | -131,424,035 |
