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 741,372,145, 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 | 741,372,145 | |
| -1 | -741,372,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 741,372,145.
Example:
1 x 741,372,145 = 741,372,145
and
-1 x -741,372,145 = 741,372,145
Notice both answers equal 741,372,145
With that explanation out of the way, let's continue. Next, we take the number 741,372,145 and divide it by 2:
741,372,145 ÷ 2 = 370,686,072.5
If the quotient is a whole number, then 2 and 370,686,072.5 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 | 741,372,145 | |
| -1 | -741,372,145 |
Now, we try dividing 741,372,145 by 3:
741,372,145 ÷ 3 = 247,124,048.3333
If the quotient is a whole number, then 3 and 247,124,048.3333 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 | 741,372,145 | |
| -1 | -741,372,145 |
Let's try dividing by 4:
741,372,145 ÷ 4 = 185,343,036.25
If the quotient is a whole number, then 4 and 185,343,036.25 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 | 741,372,145 | |
| -1 | 741,372,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 331 | 1,655 | 12,107 | 12,247 | 60,535 | 61,235 | 447,959 | 2,239,795 | 4,007,417 | 20,037,085 | 148,274,429 | 741,372,145 |
| -1 | -5 | -37 | -185 | -331 | -1,655 | -12,107 | -12,247 | -60,535 | -61,235 | -447,959 | -2,239,795 | -4,007,417 | -20,037,085 | -148,274,429 | -741,372,145 |
