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 741,451,205, 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 | 741,451,205 | |
| -1 | -741,451,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 741,451,205.
Example:
1 x 741,451,205 = 741,451,205
and
-1 x -741,451,205 = 741,451,205
Notice both answers equal 741,451,205
With that explanation out of the way, let's continue. Next, we take the number 741,451,205 and divide it by 2:
741,451,205 ÷ 2 = 370,725,602.5
If the quotient is a whole number, then 2 and 370,725,602.5 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 | 741,451,205 | |
| -1 | -741,451,205 |
Now, we try dividing 741,451,205 by 3:
741,451,205 ÷ 3 = 247,150,401.6667
If the quotient is a whole number, then 3 and 247,150,401.6667 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 | 741,451,205 | |
| -1 | -741,451,205 |
Let's try dividing by 4:
741,451,205 ÷ 4 = 185,362,801.25
If the quotient is a whole number, then 4 and 185,362,801.25 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 | 741,451,205 | |
| -1 | 741,451,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 701 | 3,505 | 7,711 | 19,231 | 38,555 | 96,155 | 211,541 | 1,057,705 | 13,480,931 | 67,404,655 | 148,290,241 | 741,451,205 |
| -1 | -5 | -11 | -55 | -701 | -3,505 | -7,711 | -19,231 | -38,555 | -96,155 | -211,541 | -1,057,705 | -13,480,931 | -67,404,655 | -148,290,241 | -741,451,205 |
