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 78,355,043, 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 | 78,355,043 | |
| -1 | -78,355,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 78,355,043.
Example:
1 x 78,355,043 = 78,355,043
and
-1 x -78,355,043 = 78,355,043
Notice both answers equal 78,355,043
With that explanation out of the way, let's continue. Next, we take the number 78,355,043 and divide it by 2:
78,355,043 ÷ 2 = 39,177,521.5
If the quotient is a whole number, then 2 and 39,177,521.5 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 | 78,355,043 | |
| -1 | -78,355,043 |
Now, we try dividing 78,355,043 by 3:
78,355,043 ÷ 3 = 26,118,347.6667
If the quotient is a whole number, then 3 and 26,118,347.6667 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 | 78,355,043 | |
| -1 | -78,355,043 |
Let's try dividing by 4:
78,355,043 ÷ 4 = 19,588,760.75
If the quotient is a whole number, then 4 and 19,588,760.75 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 | 78,355,043 | |
| -1 | 78,355,043 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 271 | 299 | 967 | 3,523 | 6,233 | 12,571 | 22,241 | 81,029 | 262,057 | 289,133 | 3,406,741 | 6,027,311 | 78,355,043 |
| -1 | -13 | -23 | -271 | -299 | -967 | -3,523 | -6,233 | -12,571 | -22,241 | -81,029 | -262,057 | -289,133 | -3,406,741 | -6,027,311 | -78,355,043 |
