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 84,292,835, 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 | 84,292,835 | |
| -1 | -84,292,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,292,835.
Example:
1 x 84,292,835 = 84,292,835
and
-1 x -84,292,835 = 84,292,835
Notice both answers equal 84,292,835
With that explanation out of the way, let's continue. Next, we take the number 84,292,835 and divide it by 2:
84,292,835 ÷ 2 = 42,146,417.5
If the quotient is a whole number, then 2 and 42,146,417.5 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 | 84,292,835 | |
| -1 | -84,292,835 |
Now, we try dividing 84,292,835 by 3:
84,292,835 ÷ 3 = 28,097,611.6667
If the quotient is a whole number, then 3 and 28,097,611.6667 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 | 84,292,835 | |
| -1 | -84,292,835 |
Let's try dividing by 4:
84,292,835 ÷ 4 = 21,073,208.75
If the quotient is a whole number, then 4 and 21,073,208.75 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 | 84,292,835 | |
| -1 | 84,292,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 121 | 209 | 605 | 1,045 | 2,299 | 7,333 | 11,495 | 36,665 | 80,663 | 139,327 | 403,315 | 696,635 | 887,293 | 1,532,597 | 4,436,465 | 7,662,985 | 16,858,567 | 84,292,835 |
| -1 | -5 | -11 | -19 | -55 | -95 | -121 | -209 | -605 | -1,045 | -2,299 | -7,333 | -11,495 | -36,665 | -80,663 | -139,327 | -403,315 | -696,635 | -887,293 | -1,532,597 | -4,436,465 | -7,662,985 | -16,858,567 | -84,292,835 |
