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 76,717,075, 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 | 76,717,075 | |
| -1 | -76,717,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,717,075.
Example:
1 x 76,717,075 = 76,717,075
and
-1 x -76,717,075 = 76,717,075
Notice both answers equal 76,717,075
With that explanation out of the way, let's continue. Next, we take the number 76,717,075 and divide it by 2:
76,717,075 ÷ 2 = 38,358,537.5
If the quotient is a whole number, then 2 and 38,358,537.5 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 | 76,717,075 | |
| -1 | -76,717,075 |
Now, we try dividing 76,717,075 by 3:
76,717,075 ÷ 3 = 25,572,358.3333
If the quotient is a whole number, then 3 and 25,572,358.3333 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 | 76,717,075 | |
| -1 | -76,717,075 |
Let's try dividing by 4:
76,717,075 ÷ 4 = 19,179,268.75
If the quotient is a whole number, then 4 and 19,179,268.75 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 | 76,717,075 | |
| -1 | 76,717,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 101 | 115 | 505 | 575 | 1,321 | 2,323 | 2,525 | 6,605 | 11,615 | 30,383 | 33,025 | 58,075 | 133,421 | 151,915 | 667,105 | 759,575 | 3,068,683 | 3,335,525 | 15,343,415 | 76,717,075 |
| -1 | -5 | -23 | -25 | -101 | -115 | -505 | -575 | -1,321 | -2,323 | -2,525 | -6,605 | -11,615 | -30,383 | -33,025 | -58,075 | -133,421 | -151,915 | -667,105 | -759,575 | -3,068,683 | -3,335,525 | -15,343,415 | -76,717,075 |
