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 76,199,045, 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 | 76,199,045 | |
| -1 | -76,199,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,199,045.
Example:
1 x 76,199,045 = 76,199,045
and
-1 x -76,199,045 = 76,199,045
Notice both answers equal 76,199,045
With that explanation out of the way, let's continue. Next, we take the number 76,199,045 and divide it by 2:
76,199,045 ÷ 2 = 38,099,522.5
If the quotient is a whole number, then 2 and 38,099,522.5 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 | 76,199,045 | |
| -1 | -76,199,045 |
Now, we try dividing 76,199,045 by 3:
76,199,045 ÷ 3 = 25,399,681.6667
If the quotient is a whole number, then 3 and 25,399,681.6667 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 | 76,199,045 | |
| -1 | -76,199,045 |
Let's try dividing by 4:
76,199,045 ÷ 4 = 19,049,761.25
If the quotient is a whole number, then 4 and 19,049,761.25 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 | 76,199,045 | |
| -1 | 76,199,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 293 | 1,465 | 3,809 | 4,001 | 19,045 | 20,005 | 52,013 | 260,065 | 1,172,293 | 5,861,465 | 15,239,809 | 76,199,045 |
| -1 | -5 | -13 | -65 | -293 | -1,465 | -3,809 | -4,001 | -19,045 | -20,005 | -52,013 | -260,065 | -1,172,293 | -5,861,465 | -15,239,809 | -76,199,045 |
