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 137,303,033, 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 | 137,303,033 | |
| -1 | -137,303,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,303,033.
Example:
1 x 137,303,033 = 137,303,033
and
-1 x -137,303,033 = 137,303,033
Notice both answers equal 137,303,033
With that explanation out of the way, let's continue. Next, we take the number 137,303,033 and divide it by 2:
137,303,033 ÷ 2 = 68,651,516.5
If the quotient is a whole number, then 2 and 68,651,516.5 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 | 137,303,033 | |
| -1 | -137,303,033 |
Now, we try dividing 137,303,033 by 3:
137,303,033 ÷ 3 = 45,767,677.6667
If the quotient is a whole number, then 3 and 45,767,677.6667 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 | 137,303,033 | |
| -1 | -137,303,033 |
Let's try dividing by 4:
137,303,033 ÷ 4 = 34,325,758.25
If the quotient is a whole number, then 4 and 34,325,758.25 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 | 137,303,033 | |
| -1 | 137,303,033 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 67 | 119 | 289 | 469 | 1,013 | 1,139 | 2,023 | 7,091 | 7,973 | 17,221 | 19,363 | 67,871 | 120,547 | 135,541 | 292,757 | 475,097 | 1,153,807 | 2,049,299 | 8,076,649 | 19,614,719 | 137,303,033 |
| -1 | -7 | -17 | -67 | -119 | -289 | -469 | -1,013 | -1,139 | -2,023 | -7,091 | -7,973 | -17,221 | -19,363 | -67,871 | -120,547 | -135,541 | -292,757 | -475,097 | -1,153,807 | -2,049,299 | -8,076,649 | -19,614,719 | -137,303,033 |
