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 79,194,185, 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 | 79,194,185 | |
| -1 | -79,194,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 79,194,185.
Example:
1 x 79,194,185 = 79,194,185
and
-1 x -79,194,185 = 79,194,185
Notice both answers equal 79,194,185
With that explanation out of the way, let's continue. Next, we take the number 79,194,185 and divide it by 2:
79,194,185 ÷ 2 = 39,597,092.5
If the quotient is a whole number, then 2 and 39,597,092.5 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 | 79,194,185 | |
| -1 | -79,194,185 |
Now, we try dividing 79,194,185 by 3:
79,194,185 ÷ 3 = 26,398,061.6667
If the quotient is a whole number, then 3 and 26,398,061.6667 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 | 79,194,185 | |
| -1 | -79,194,185 |
Let's try dividing by 4:
79,194,185 ÷ 4 = 19,798,546.25
If the quotient is a whole number, then 4 and 19,798,546.25 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 | 79,194,185 | |
| -1 | 79,194,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 119,089 | 595,445 | 833,623 | 2,262,691 | 4,168,115 | 11,313,455 | 15,838,837 | 79,194,185 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -119,089 | -595,445 | -833,623 | -2,262,691 | -4,168,115 | -11,313,455 | -15,838,837 | -79,194,185 |
