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 76,609,235, 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 | 76,609,235 | |
| -1 | -76,609,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,609,235.
Example:
1 x 76,609,235 = 76,609,235
and
-1 x -76,609,235 = 76,609,235
Notice both answers equal 76,609,235
With that explanation out of the way, let's continue. Next, we take the number 76,609,235 and divide it by 2:
76,609,235 ÷ 2 = 38,304,617.5
If the quotient is a whole number, then 2 and 38,304,617.5 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 | 76,609,235 | |
| -1 | -76,609,235 |
Now, we try dividing 76,609,235 by 3:
76,609,235 ÷ 3 = 25,536,411.6667
If the quotient is a whole number, then 3 and 25,536,411.6667 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 | 76,609,235 | |
| -1 | -76,609,235 |
Let's try dividing by 4:
76,609,235 ÷ 4 = 19,152,308.75
If the quotient is a whole number, then 4 and 19,152,308.75 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 | 76,609,235 | |
| -1 | 76,609,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 233 | 1,165 | 3,461 | 4,427 | 17,305 | 22,135 | 65,759 | 328,795 | 806,413 | 4,032,065 | 15,321,847 | 76,609,235 |
| -1 | -5 | -19 | -95 | -233 | -1,165 | -3,461 | -4,427 | -17,305 | -22,135 | -65,759 | -328,795 | -806,413 | -4,032,065 | -15,321,847 | -76,609,235 |
