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 79,657,027, 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 | 79,657,027 | |
| -1 | -79,657,027 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 79,657,027.
Example:
1 x 79,657,027 = 79,657,027
and
-1 x -79,657,027 = 79,657,027
Notice both answers equal 79,657,027
With that explanation out of the way, let's continue. Next, we take the number 79,657,027 and divide it by 2:
79,657,027 ÷ 2 = 39,828,513.5
If the quotient is a whole number, then 2 and 39,828,513.5 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 | 79,657,027 | |
| -1 | -79,657,027 |
Now, we try dividing 79,657,027 by 3:
79,657,027 ÷ 3 = 26,552,342.3333
If the quotient is a whole number, then 3 and 26,552,342.3333 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 | 79,657,027 | |
| -1 | -79,657,027 |
Let's try dividing by 4:
79,657,027 ÷ 4 = 19,914,256.75
If the quotient is a whole number, then 4 and 19,914,256.75 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 | 79,657,027 | |
| -1 | 79,657,027 |
If you did it right, you will end up with this table:
| 1 | 23 | 43 | 239 | 337 | 989 | 5,497 | 7,751 | 10,277 | 14,491 | 80,543 | 236,371 | 333,293 | 1,852,489 | 3,463,349 | 79,657,027 |
| -1 | -23 | -43 | -239 | -337 | -989 | -5,497 | -7,751 | -10,277 | -14,491 | -80,543 | -236,371 | -333,293 | -1,852,489 | -3,463,349 | -79,657,027 |
