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 85,482,265, 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 | 85,482,265 | |
| -1 | -85,482,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 85,482,265.
Example:
1 x 85,482,265 = 85,482,265
and
-1 x -85,482,265 = 85,482,265
Notice both answers equal 85,482,265
With that explanation out of the way, let's continue. Next, we take the number 85,482,265 and divide it by 2:
85,482,265 ÷ 2 = 42,741,132.5
If the quotient is a whole number, then 2 and 42,741,132.5 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 | 85,482,265 | |
| -1 | -85,482,265 |
Now, we try dividing 85,482,265 by 3:
85,482,265 ÷ 3 = 28,494,088.3333
If the quotient is a whole number, then 3 and 28,494,088.3333 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 | 85,482,265 | |
| -1 | -85,482,265 |
Let's try dividing by 4:
85,482,265 ÷ 4 = 21,370,566.25
If the quotient is a whole number, then 4 and 21,370,566.25 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 | 85,482,265 | |
| -1 | 85,482,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 121 | 229 | 605 | 617 | 1,145 | 2,519 | 3,085 | 6,787 | 12,595 | 27,709 | 33,935 | 74,657 | 138,545 | 141,293 | 373,285 | 706,465 | 1,554,223 | 7,771,115 | 17,096,453 | 85,482,265 |
| -1 | -5 | -11 | -55 | -121 | -229 | -605 | -617 | -1,145 | -2,519 | -3,085 | -6,787 | -12,595 | -27,709 | -33,935 | -74,657 | -138,545 | -141,293 | -373,285 | -706,465 | -1,554,223 | -7,771,115 | -17,096,453 | -85,482,265 |
