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 76,236,313, 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 | 76,236,313 | |
| -1 | -76,236,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,236,313.
Example:
1 x 76,236,313 = 76,236,313
and
-1 x -76,236,313 = 76,236,313
Notice both answers equal 76,236,313
With that explanation out of the way, let's continue. Next, we take the number 76,236,313 and divide it by 2:
76,236,313 ÷ 2 = 38,118,156.5
If the quotient is a whole number, then 2 and 38,118,156.5 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 | 76,236,313 | |
| -1 | -76,236,313 |
Now, we try dividing 76,236,313 by 3:
76,236,313 ÷ 3 = 25,412,104.3333
If the quotient is a whole number, then 3 and 25,412,104.3333 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 | 76,236,313 | |
| -1 | -76,236,313 |
Let's try dividing by 4:
76,236,313 ÷ 4 = 19,059,078.25
If the quotient is a whole number, then 4 and 19,059,078.25 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 | 76,236,313 | |
| -1 | 76,236,313 |
If you did it right, you will end up with this table:
| 1 | 17 | 53 | 191 | 443 | 901 | 3,247 | 7,531 | 10,123 | 23,479 | 84,613 | 172,091 | 399,143 | 1,438,421 | 4,484,489 | 76,236,313 |
| -1 | -17 | -53 | -191 | -443 | -901 | -3,247 | -7,531 | -10,123 | -23,479 | -84,613 | -172,091 | -399,143 | -1,438,421 | -4,484,489 | -76,236,313 |
