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 137,334,047, 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 | 137,334,047 | |
| -1 | -137,334,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,334,047.
Example:
1 x 137,334,047 = 137,334,047
and
-1 x -137,334,047 = 137,334,047
Notice both answers equal 137,334,047
With that explanation out of the way, let's continue. Next, we take the number 137,334,047 and divide it by 2:
137,334,047 ÷ 2 = 68,667,023.5
If the quotient is a whole number, then 2 and 68,667,023.5 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 | 137,334,047 | |
| -1 | -137,334,047 |
Now, we try dividing 137,334,047 by 3:
137,334,047 ÷ 3 = 45,778,015.6667
If the quotient is a whole number, then 3 and 45,778,015.6667 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 | 137,334,047 | |
| -1 | -137,334,047 |
Let's try dividing by 4:
137,334,047 ÷ 4 = 34,333,511.75
If the quotient is a whole number, then 4 and 34,333,511.75 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 | 137,334,047 | |
| -1 | 137,334,047 |
If you did it right, you will end up with this table:
| 1 | 37 | 47 | 151 | 523 | 1,739 | 5,587 | 7,097 | 19,351 | 24,581 | 78,973 | 262,589 | 909,497 | 2,922,001 | 3,711,731 | 137,334,047 |
| -1 | -37 | -47 | -151 | -523 | -1,739 | -5,587 | -7,097 | -19,351 | -24,581 | -78,973 | -262,589 | -909,497 | -2,922,001 | -3,711,731 | -137,334,047 |
