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 741,380,137, 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 | 741,380,137 | |
| -1 | -741,380,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 741,380,137.
Example:
1 x 741,380,137 = 741,380,137
and
-1 x -741,380,137 = 741,380,137
Notice both answers equal 741,380,137
With that explanation out of the way, let's continue. Next, we take the number 741,380,137 and divide it by 2:
741,380,137 ÷ 2 = 370,690,068.5
If the quotient is a whole number, then 2 and 370,690,068.5 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 | 741,380,137 | |
| -1 | -741,380,137 |
Now, we try dividing 741,380,137 by 3:
741,380,137 ÷ 3 = 247,126,712.3333
If the quotient is a whole number, then 3 and 247,126,712.3333 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 | 741,380,137 | |
| -1 | -741,380,137 |
Let's try dividing by 4:
741,380,137 ÷ 4 = 185,345,034.25
If the quotient is a whole number, then 4 and 185,345,034.25 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 | 741,380,137 | |
| -1 | 741,380,137 |
If you did it right, you will end up with this table:
| 1 | 23 | 37 | 233 | 851 | 3,739 | 5,359 | 8,621 | 85,997 | 138,343 | 198,283 | 871,187 | 3,181,889 | 20,037,301 | 32,233,919 | 741,380,137 |
| -1 | -23 | -37 | -233 | -851 | -3,739 | -5,359 | -8,621 | -85,997 | -138,343 | -198,283 | -871,187 | -3,181,889 | -20,037,301 | -32,233,919 | -741,380,137 |
