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 84,713,483, 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 | 84,713,483 | |
| -1 | -84,713,483 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,713,483.
Example:
1 x 84,713,483 = 84,713,483
and
-1 x -84,713,483 = 84,713,483
Notice both answers equal 84,713,483
With that explanation out of the way, let's continue. Next, we take the number 84,713,483 and divide it by 2:
84,713,483 ÷ 2 = 42,356,741.5
If the quotient is a whole number, then 2 and 42,356,741.5 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 | 84,713,483 | |
| -1 | -84,713,483 |
Now, we try dividing 84,713,483 by 3:
84,713,483 ÷ 3 = 28,237,827.6667
If the quotient is a whole number, then 3 and 28,237,827.6667 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 | 84,713,483 | |
| -1 | -84,713,483 |
Let's try dividing by 4:
84,713,483 ÷ 4 = 21,178,370.75
If the quotient is a whole number, then 4 and 21,178,370.75 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 | 84,713,483 | |
| -1 | 84,713,483 |
If you did it right, you will end up with this table:
| 1 | 31 | 43 | 103 | 617 | 1,333 | 3,193 | 4,429 | 19,127 | 26,531 | 63,551 | 137,299 | 822,461 | 1,970,081 | 2,732,693 | 84,713,483 |
| -1 | -31 | -43 | -103 | -617 | -1,333 | -3,193 | -4,429 | -19,127 | -26,531 | -63,551 | -137,299 | -822,461 | -1,970,081 | -2,732,693 | -84,713,483 |
