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 75,457,333, 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 | 75,457,333 | |
| -1 | -75,457,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,457,333.
Example:
1 x 75,457,333 = 75,457,333
and
-1 x -75,457,333 = 75,457,333
Notice both answers equal 75,457,333
With that explanation out of the way, let's continue. Next, we take the number 75,457,333 and divide it by 2:
75,457,333 ÷ 2 = 37,728,666.5
If the quotient is a whole number, then 2 and 37,728,666.5 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 | 75,457,333 | |
| -1 | -75,457,333 |
Now, we try dividing 75,457,333 by 3:
75,457,333 ÷ 3 = 25,152,444.3333
If the quotient is a whole number, then 3 and 25,152,444.3333 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 | 75,457,333 | |
| -1 | -75,457,333 |
Let's try dividing by 4:
75,457,333 ÷ 4 = 18,864,333.25
If the quotient is a whole number, then 4 and 18,864,333.25 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 | 75,457,333 | |
| -1 | 75,457,333 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 337 | 1,103 | 2,359 | 7,721 | 9,773 | 31,987 | 68,411 | 223,909 | 371,711 | 2,601,977 | 10,779,619 | 75,457,333 |
| -1 | -7 | -29 | -203 | -337 | -1,103 | -2,359 | -7,721 | -9,773 | -31,987 | -68,411 | -223,909 | -371,711 | -2,601,977 | -10,779,619 | -75,457,333 |
