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 85,482,145, 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 | 85,482,145 | |
| -1 | -85,482,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 85,482,145.
Example:
1 x 85,482,145 = 85,482,145
and
-1 x -85,482,145 = 85,482,145
Notice both answers equal 85,482,145
With that explanation out of the way, let's continue. Next, we take the number 85,482,145 and divide it by 2:
85,482,145 ÷ 2 = 42,741,072.5
If the quotient is a whole number, then 2 and 42,741,072.5 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 | 85,482,145 | |
| -1 | -85,482,145 |
Now, we try dividing 85,482,145 by 3:
85,482,145 ÷ 3 = 28,494,048.3333
If the quotient is a whole number, then 3 and 28,494,048.3333 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 | 85,482,145 | |
| -1 | -85,482,145 |
Let's try dividing by 4:
85,482,145 ÷ 4 = 21,370,536.25
If the quotient is a whole number, then 4 and 21,370,536.25 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 | 85,482,145 | |
| -1 | 85,482,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 106,189 | 530,945 | 743,323 | 2,442,347 | 3,716,615 | 12,211,735 | 17,096,429 | 85,482,145 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -106,189 | -530,945 | -743,323 | -2,442,347 | -3,716,615 | -12,211,735 | -17,096,429 | -85,482,145 |
