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 79,112,941, 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 | 79,112,941 | |
| -1 | -79,112,941 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 79,112,941.
Example:
1 x 79,112,941 = 79,112,941
and
-1 x -79,112,941 = 79,112,941
Notice both answers equal 79,112,941
With that explanation out of the way, let's continue. Next, we take the number 79,112,941 and divide it by 2:
79,112,941 ÷ 2 = 39,556,470.5
If the quotient is a whole number, then 2 and 39,556,470.5 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 | 79,112,941 | |
| -1 | -79,112,941 |
Now, we try dividing 79,112,941 by 3:
79,112,941 ÷ 3 = 26,370,980.3333
If the quotient is a whole number, then 3 and 26,370,980.3333 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 | 79,112,941 | |
| -1 | -79,112,941 |
Let's try dividing by 4:
79,112,941 ÷ 4 = 19,778,235.25
If the quotient is a whole number, then 4 and 19,778,235.25 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 | 79,112,941 | |
| -1 | 79,112,941 |
If you did it right, you will end up with this table:
| 1 | 19 | 53 | 251 | 313 | 1,007 | 4,769 | 5,947 | 13,303 | 16,589 | 78,563 | 252,757 | 315,191 | 1,492,697 | 4,163,839 | 79,112,941 |
| -1 | -19 | -53 | -251 | -313 | -1,007 | -4,769 | -5,947 | -13,303 | -16,589 | -78,563 | -252,757 | -315,191 | -1,492,697 | -4,163,839 | -79,112,941 |
