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 137,382,035, 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 | 137,382,035 | |
| -1 | -137,382,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,382,035.
Example:
1 x 137,382,035 = 137,382,035
and
-1 x -137,382,035 = 137,382,035
Notice both answers equal 137,382,035
With that explanation out of the way, let's continue. Next, we take the number 137,382,035 and divide it by 2:
137,382,035 ÷ 2 = 68,691,017.5
If the quotient is a whole number, then 2 and 68,691,017.5 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 | 137,382,035 | |
| -1 | -137,382,035 |
Now, we try dividing 137,382,035 by 3:
137,382,035 ÷ 3 = 45,794,011.6667
If the quotient is a whole number, then 3 and 45,794,011.6667 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 | 137,382,035 | |
| -1 | -137,382,035 |
Let's try dividing by 4:
137,382,035 ÷ 4 = 34,345,508.75
If the quotient is a whole number, then 4 and 34,345,508.75 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 | 137,382,035 | |
| -1 | 137,382,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 683 | 821 | 3,415 | 4,105 | 4,781 | 5,747 | 23,905 | 28,735 | 33,467 | 40,229 | 167,335 | 201,145 | 560,743 | 2,803,715 | 3,925,201 | 19,626,005 | 27,476,407 | 137,382,035 |
| -1 | -5 | -7 | -35 | -49 | -245 | -683 | -821 | -3,415 | -4,105 | -4,781 | -5,747 | -23,905 | -28,735 | -33,467 | -40,229 | -167,335 | -201,145 | -560,743 | -2,803,715 | -3,925,201 | -19,626,005 | -27,476,407 | -137,382,035 |
