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 79,272,865, 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 | 79,272,865 | |
| -1 | -79,272,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 79,272,865.
Example:
1 x 79,272,865 = 79,272,865
and
-1 x -79,272,865 = 79,272,865
Notice both answers equal 79,272,865
With that explanation out of the way, let's continue. Next, we take the number 79,272,865 and divide it by 2:
79,272,865 ÷ 2 = 39,636,432.5
If the quotient is a whole number, then 2 and 39,636,432.5 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 | 79,272,865 | |
| -1 | -79,272,865 |
Now, we try dividing 79,272,865 by 3:
79,272,865 ÷ 3 = 26,424,288.3333
If the quotient is a whole number, then 3 and 26,424,288.3333 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 | 79,272,865 | |
| -1 | -79,272,865 |
Let's try dividing by 4:
79,272,865 ÷ 4 = 19,818,216.25
If the quotient is a whole number, then 4 and 19,818,216.25 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 | 79,272,865 | |
| -1 | 79,272,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 52,673 | 263,365 | 368,711 | 1,843,555 | 2,264,939 | 11,324,695 | 15,854,573 | 79,272,865 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -52,673 | -263,365 | -368,711 | -1,843,555 | -2,264,939 | -11,324,695 | -15,854,573 | -79,272,865 |
