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 76,803,601, 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 | 76,803,601 | |
| -1 | -76,803,601 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,803,601.
Example:
1 x 76,803,601 = 76,803,601
and
-1 x -76,803,601 = 76,803,601
Notice both answers equal 76,803,601
With that explanation out of the way, let's continue. Next, we take the number 76,803,601 and divide it by 2:
76,803,601 ÷ 2 = 38,401,800.5
If the quotient is a whole number, then 2 and 38,401,800.5 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 | 76,803,601 | |
| -1 | -76,803,601 |
Now, we try dividing 76,803,601 by 3:
76,803,601 ÷ 3 = 25,601,200.3333
If the quotient is a whole number, then 3 and 25,601,200.3333 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 | 76,803,601 | |
| -1 | -76,803,601 |
Let's try dividing by 4:
76,803,601 ÷ 4 = 19,200,900.25
If the quotient is a whole number, then 4 and 19,200,900.25 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 | 76,803,601 | |
| -1 | 76,803,601 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 37 | 161 | 259 | 851 | 5,957 | 12,893 | 90,251 | 296,539 | 477,041 | 2,075,773 | 3,339,287 | 10,971,943 | 76,803,601 |
| -1 | -7 | -23 | -37 | -161 | -259 | -851 | -5,957 | -12,893 | -90,251 | -296,539 | -477,041 | -2,075,773 | -3,339,287 | -10,971,943 | -76,803,601 |
