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 75,061,535, 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 | 75,061,535 | |
| -1 | -75,061,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,061,535.
Example:
1 x 75,061,535 = 75,061,535
and
-1 x -75,061,535 = 75,061,535
Notice both answers equal 75,061,535
With that explanation out of the way, let's continue. Next, we take the number 75,061,535 and divide it by 2:
75,061,535 ÷ 2 = 37,530,767.5
If the quotient is a whole number, then 2 and 37,530,767.5 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 | 75,061,535 | |
| -1 | -75,061,535 |
Now, we try dividing 75,061,535 by 3:
75,061,535 ÷ 3 = 25,020,511.6667
If the quotient is a whole number, then 3 and 25,020,511.6667 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 | 75,061,535 | |
| -1 | -75,061,535 |
Let's try dividing by 4:
75,061,535 ÷ 4 = 18,765,383.75
If the quotient is a whole number, then 4 and 18,765,383.75 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 | 75,061,535 | |
| -1 | 75,061,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 239 | 1,195 | 2,731 | 5,497 | 13,655 | 27,485 | 62,813 | 314,065 | 652,709 | 3,263,545 | 15,012,307 | 75,061,535 |
| -1 | -5 | -23 | -115 | -239 | -1,195 | -2,731 | -5,497 | -13,655 | -27,485 | -62,813 | -314,065 | -652,709 | -3,263,545 | -15,012,307 | -75,061,535 |
