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 75,790,897, 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 | 75,790,897 | |
| -1 | -75,790,897 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,790,897.
Example:
1 x 75,790,897 = 75,790,897
and
-1 x -75,790,897 = 75,790,897
Notice both answers equal 75,790,897
With that explanation out of the way, let's continue. Next, we take the number 75,790,897 and divide it by 2:
75,790,897 ÷ 2 = 37,895,448.5
If the quotient is a whole number, then 2 and 37,895,448.5 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 | 75,790,897 | |
| -1 | -75,790,897 |
Now, we try dividing 75,790,897 by 3:
75,790,897 ÷ 3 = 25,263,632.3333
If the quotient is a whole number, then 3 and 25,263,632.3333 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 | 75,790,897 | |
| -1 | -75,790,897 |
Let's try dividing by 4:
75,790,897 ÷ 4 = 18,947,724.25
If the quotient is a whole number, then 4 and 18,947,724.25 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 | 75,790,897 | |
| -1 | 75,790,897 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 43 | 49 | 91 | 301 | 559 | 637 | 2,107 | 2,767 | 3,913 | 19,369 | 27,391 | 35,971 | 118,981 | 135,583 | 251,797 | 832,867 | 1,546,753 | 1,762,579 | 5,830,069 | 10,827,271 | 75,790,897 |
| -1 | -7 | -13 | -43 | -49 | -91 | -301 | -559 | -637 | -2,107 | -2,767 | -3,913 | -19,369 | -27,391 | -35,971 | -118,981 | -135,583 | -251,797 | -832,867 | -1,546,753 | -1,762,579 | -5,830,069 | -10,827,271 | -75,790,897 |
