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 75,235,825, 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 | 75,235,825 | |
| -1 | -75,235,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,235,825.
Example:
1 x 75,235,825 = 75,235,825
and
-1 x -75,235,825 = 75,235,825
Notice both answers equal 75,235,825
With that explanation out of the way, let's continue. Next, we take the number 75,235,825 and divide it by 2:
75,235,825 ÷ 2 = 37,617,912.5
If the quotient is a whole number, then 2 and 37,617,912.5 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 | 75,235,825 | |
| -1 | -75,235,825 |
Now, we try dividing 75,235,825 by 3:
75,235,825 ÷ 3 = 25,078,608.3333
If the quotient is a whole number, then 3 and 25,078,608.3333 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 | 75,235,825 | |
| -1 | -75,235,825 |
Let's try dividing by 4:
75,235,825 ÷ 4 = 18,808,956.25
If the quotient is a whole number, then 4 and 18,808,956.25 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 | 75,235,825 | |
| -1 | 75,235,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 61,417 | 307,085 | 429,919 | 1,535,425 | 2,149,595 | 3,009,433 | 10,747,975 | 15,047,165 | 75,235,825 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -61,417 | -307,085 | -429,919 | -1,535,425 | -2,149,595 | -3,009,433 | -10,747,975 | -15,047,165 | -75,235,825 |
