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 137,377,445, 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 | 137,377,445 | |
| -1 | -137,377,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,377,445.
Example:
1 x 137,377,445 = 137,377,445
and
-1 x -137,377,445 = 137,377,445
Notice both answers equal 137,377,445
With that explanation out of the way, let's continue. Next, we take the number 137,377,445 and divide it by 2:
137,377,445 ÷ 2 = 68,688,722.5
If the quotient is a whole number, then 2 and 68,688,722.5 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 | 137,377,445 | |
| -1 | -137,377,445 |
Now, we try dividing 137,377,445 by 3:
137,377,445 ÷ 3 = 45,792,481.6667
If the quotient is a whole number, then 3 and 45,792,481.6667 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 | 137,377,445 | |
| -1 | -137,377,445 |
Let's try dividing by 4:
137,377,445 ÷ 4 = 34,344,361.25
If the quotient is a whole number, then 4 and 34,344,361.25 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 | 137,377,445 | |
| -1 | 137,377,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 293 | 395 | 1,187 | 1,465 | 5,935 | 23,147 | 93,773 | 115,735 | 347,791 | 468,865 | 1,738,955 | 27,475,489 | 137,377,445 |
| -1 | -5 | -79 | -293 | -395 | -1,187 | -1,465 | -5,935 | -23,147 | -93,773 | -115,735 | -347,791 | -468,865 | -1,738,955 | -27,475,489 | -137,377,445 |
