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 75,505,625, 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 | 75,505,625 | |
| -1 | -75,505,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,505,625.
Example:
1 x 75,505,625 = 75,505,625
and
-1 x -75,505,625 = 75,505,625
Notice both answers equal 75,505,625
With that explanation out of the way, let's continue. Next, we take the number 75,505,625 and divide it by 2:
75,505,625 ÷ 2 = 37,752,812.5
If the quotient is a whole number, then 2 and 37,752,812.5 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 | 75,505,625 | |
| -1 | -75,505,625 |
Now, we try dividing 75,505,625 by 3:
75,505,625 ÷ 3 = 25,168,541.6667
If the quotient is a whole number, then 3 and 25,168,541.6667 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 | 75,505,625 | |
| -1 | -75,505,625 |
Let's try dividing by 4:
75,505,625 ÷ 4 = 18,876,406.25
If the quotient is a whole number, then 4 and 18,876,406.25 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 | 75,505,625 | |
| -1 | 75,505,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 625 | 1,625 | 8,125 | 9,293 | 46,465 | 120,809 | 232,325 | 604,045 | 1,161,625 | 3,020,225 | 5,808,125 | 15,101,125 | 75,505,625 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -625 | -1,625 | -8,125 | -9,293 | -46,465 | -120,809 | -232,325 | -604,045 | -1,161,625 | -3,020,225 | -5,808,125 | -15,101,125 | -75,505,625 |
