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 75,841,087, 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 | 75,841,087 | |
| -1 | -75,841,087 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,841,087.
Example:
1 x 75,841,087 = 75,841,087
and
-1 x -75,841,087 = 75,841,087
Notice both answers equal 75,841,087
With that explanation out of the way, let's continue. Next, we take the number 75,841,087 and divide it by 2:
75,841,087 ÷ 2 = 37,920,543.5
If the quotient is a whole number, then 2 and 37,920,543.5 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 | 75,841,087 | |
| -1 | -75,841,087 |
Now, we try dividing 75,841,087 by 3:
75,841,087 ÷ 3 = 25,280,362.3333
If the quotient is a whole number, then 3 and 25,280,362.3333 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 | 75,841,087 | |
| -1 | -75,841,087 |
Let's try dividing by 4:
75,841,087 ÷ 4 = 18,960,271.75
If the quotient is a whole number, then 4 and 18,960,271.75 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 | 75,841,087 | |
| -1 | 75,841,087 |
If you did it right, you will end up with this table:
| 1 | 7 | 73 | 193 | 511 | 769 | 1,351 | 5,383 | 14,089 | 56,137 | 98,623 | 148,417 | 392,959 | 1,038,919 | 10,834,441 | 75,841,087 |
| -1 | -7 | -73 | -193 | -511 | -769 | -1,351 | -5,383 | -14,089 | -56,137 | -98,623 | -148,417 | -392,959 | -1,038,919 | -10,834,441 | -75,841,087 |
