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 75,862,435, 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 | 75,862,435 | |
| -1 | -75,862,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,862,435.
Example:
1 x 75,862,435 = 75,862,435
and
-1 x -75,862,435 = 75,862,435
Notice both answers equal 75,862,435
With that explanation out of the way, let's continue. Next, we take the number 75,862,435 and divide it by 2:
75,862,435 ÷ 2 = 37,931,217.5
If the quotient is a whole number, then 2 and 37,931,217.5 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 | 75,862,435 | |
| -1 | -75,862,435 |
Now, we try dividing 75,862,435 by 3:
75,862,435 ÷ 3 = 25,287,478.3333
If the quotient is a whole number, then 3 and 25,287,478.3333 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 | 75,862,435 | |
| -1 | -75,862,435 |
Let's try dividing by 4:
75,862,435 ÷ 4 = 18,965,608.75
If the quotient is a whole number, then 4 and 18,965,608.75 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 | 75,862,435 | |
| -1 | 75,862,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 71 | 355 | 781 | 3,905 | 19,427 | 97,135 | 213,697 | 1,068,485 | 1,379,317 | 6,896,585 | 15,172,487 | 75,862,435 |
| -1 | -5 | -11 | -55 | -71 | -355 | -781 | -3,905 | -19,427 | -97,135 | -213,697 | -1,068,485 | -1,379,317 | -6,896,585 | -15,172,487 | -75,862,435 |
