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 83,474,345, 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 | 83,474,345 | |
| -1 | -83,474,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,474,345.
Example:
1 x 83,474,345 = 83,474,345
and
-1 x -83,474,345 = 83,474,345
Notice both answers equal 83,474,345
With that explanation out of the way, let's continue. Next, we take the number 83,474,345 and divide it by 2:
83,474,345 ÷ 2 = 41,737,172.5
If the quotient is a whole number, then 2 and 41,737,172.5 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 | 83,474,345 | |
| -1 | -83,474,345 |
Now, we try dividing 83,474,345 by 3:
83,474,345 ÷ 3 = 27,824,781.6667
If the quotient is a whole number, then 3 and 27,824,781.6667 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 | 83,474,345 | |
| -1 | -83,474,345 |
Let's try dividing by 4:
83,474,345 ÷ 4 = 20,868,586.25
If the quotient is a whole number, then 4 and 20,868,586.25 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 | 83,474,345 | |
| -1 | 83,474,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 83 | 355 | 415 | 2,833 | 5,893 | 14,165 | 29,465 | 201,143 | 235,139 | 1,005,715 | 1,175,695 | 16,694,869 | 83,474,345 |
| -1 | -5 | -71 | -83 | -355 | -415 | -2,833 | -5,893 | -14,165 | -29,465 | -201,143 | -235,139 | -1,005,715 | -1,175,695 | -16,694,869 | -83,474,345 |
