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 84,674,735, 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 | 84,674,735 | |
| -1 | -84,674,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,674,735.
Example:
1 x 84,674,735 = 84,674,735
and
-1 x -84,674,735 = 84,674,735
Notice both answers equal 84,674,735
With that explanation out of the way, let's continue. Next, we take the number 84,674,735 and divide it by 2:
84,674,735 ÷ 2 = 42,337,367.5
If the quotient is a whole number, then 2 and 42,337,367.5 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 | 84,674,735 | |
| -1 | -84,674,735 |
Now, we try dividing 84,674,735 by 3:
84,674,735 ÷ 3 = 28,224,911.6667
If the quotient is a whole number, then 3 and 28,224,911.6667 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 | 84,674,735 | |
| -1 | -84,674,735 |
Let's try dividing by 4:
84,674,735 ÷ 4 = 21,168,683.75
If the quotient is a whole number, then 4 and 21,168,683.75 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 | 84,674,735 | |
| -1 | 84,674,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 59 | 95 | 295 | 1,121 | 5,605 | 15,107 | 75,535 | 287,033 | 891,313 | 1,435,165 | 4,456,565 | 16,934,947 | 84,674,735 |
| -1 | -5 | -19 | -59 | -95 | -295 | -1,121 | -5,605 | -15,107 | -75,535 | -287,033 | -891,313 | -1,435,165 | -4,456,565 | -16,934,947 | -84,674,735 |
