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 75,300,467, 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 | 75,300,467 | |
| -1 | -75,300,467 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,300,467.
Example:
1 x 75,300,467 = 75,300,467
and
-1 x -75,300,467 = 75,300,467
Notice both answers equal 75,300,467
With that explanation out of the way, let's continue. Next, we take the number 75,300,467 and divide it by 2:
75,300,467 ÷ 2 = 37,650,233.5
If the quotient is a whole number, then 2 and 37,650,233.5 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 | 75,300,467 | |
| -1 | -75,300,467 |
Now, we try dividing 75,300,467 by 3:
75,300,467 ÷ 3 = 25,100,155.6667
If the quotient is a whole number, then 3 and 25,100,155.6667 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 | 75,300,467 | |
| -1 | -75,300,467 |
Let's try dividing by 4:
75,300,467 ÷ 4 = 18,825,116.75
If the quotient is a whole number, then 4 and 18,825,116.75 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 | 75,300,467 | |
| -1 | 75,300,467 |
If you did it right, you will end up with this table:
| 1 | 11 | 167 | 179 | 229 | 1,837 | 1,969 | 2,519 | 29,893 | 38,243 | 40,991 | 328,823 | 420,673 | 450,901 | 6,845,497 | 75,300,467 |
| -1 | -11 | -167 | -179 | -229 | -1,837 | -1,969 | -2,519 | -29,893 | -38,243 | -40,991 | -328,823 | -420,673 | -450,901 | -6,845,497 | -75,300,467 |
