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 79,242,907, 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 | 79,242,907 | |
-1 | -79,242,907 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 79,242,907.
Example:
1 x 79,242,907 = 79,242,907
and
-1 x -79,242,907 = 79,242,907
Notice both answers equal 79,242,907
With that explanation out of the way, let's continue. Next, we take the number 79,242,907 and divide it by 2:
79,242,907 ÷ 2 = 39,621,453.5
If the quotient is a whole number, then 2 and 39,621,453.5 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 | 79,242,907 | |
-1 | -79,242,907 |
Now, we try dividing 79,242,907 by 3:
79,242,907 ÷ 3 = 26,414,302.3333
If the quotient is a whole number, then 3 and 26,414,302.3333 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 | 79,242,907 | |
-1 | -79,242,907 |
Let's try dividing by 4:
79,242,907 ÷ 4 = 19,810,726.75
If the quotient is a whole number, then 4 and 19,810,726.75 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 | 79,242,907 | |
-1 | 79,242,907 |
If you did it right, you will end up with this table:
1 | 1,061 | 74,687 | 79,242,907 |
-1 | -1,061 | -74,687 | -79,242,907 |
