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 137,334,043, 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 | 137,334,043 | |
| -1 | -137,334,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,334,043.
Example:
1 x 137,334,043 = 137,334,043
and
-1 x -137,334,043 = 137,334,043
Notice both answers equal 137,334,043
With that explanation out of the way, let's continue. Next, we take the number 137,334,043 and divide it by 2:
137,334,043 ÷ 2 = 68,667,021.5
If the quotient is a whole number, then 2 and 68,667,021.5 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 | 137,334,043 | |
| -1 | -137,334,043 |
Now, we try dividing 137,334,043 by 3:
137,334,043 ÷ 3 = 45,778,014.3333
If the quotient is a whole number, then 3 and 45,778,014.3333 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 | 137,334,043 | |
| -1 | -137,334,043 |
Let's try dividing by 4:
137,334,043 ÷ 4 = 34,333,510.75
If the quotient is a whole number, then 4 and 34,333,510.75 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 | 137,334,043 | |
| -1 | 137,334,043 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 101 | 707 | 1,111 | 7,777 | 17,659 | 123,613 | 194,249 | 1,359,743 | 1,783,559 | 12,484,913 | 19,619,149 | 137,334,043 |
| -1 | -7 | -11 | -77 | -101 | -707 | -1,111 | -7,777 | -17,659 | -123,613 | -194,249 | -1,359,743 | -1,783,559 | -12,484,913 | -19,619,149 | -137,334,043 |
