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 741,374,543, 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 | 741,374,543 | |
| -1 | -741,374,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 741,374,543.
Example:
1 x 741,374,543 = 741,374,543
and
-1 x -741,374,543 = 741,374,543
Notice both answers equal 741,374,543
With that explanation out of the way, let's continue. Next, we take the number 741,374,543 and divide it by 2:
741,374,543 ÷ 2 = 370,687,271.5
If the quotient is a whole number, then 2 and 370,687,271.5 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 | 741,374,543 | |
| -1 | -741,374,543 |
Now, we try dividing 741,374,543 by 3:
741,374,543 ÷ 3 = 247,124,847.6667
If the quotient is a whole number, then 3 and 247,124,847.6667 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 | 741,374,543 | |
| -1 | -741,374,543 |
Let's try dividing by 4:
741,374,543 ÷ 4 = 185,343,635.75
If the quotient is a whole number, then 4 and 185,343,635.75 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 | 741,374,543 | |
| -1 | 741,374,543 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 587 | 4,109 | 7,631 | 13,879 | 53,417 | 97,153 | 180,427 | 1,262,989 | 8,146,973 | 57,028,811 | 105,910,649 | 741,374,543 |
| -1 | -7 | -13 | -91 | -587 | -4,109 | -7,631 | -13,879 | -53,417 | -97,153 | -180,427 | -1,262,989 | -8,146,973 | -57,028,811 | -105,910,649 | -741,374,543 |
