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 85,382,255, 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 | 85,382,255 | |
| -1 | -85,382,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 85,382,255.
Example:
1 x 85,382,255 = 85,382,255
and
-1 x -85,382,255 = 85,382,255
Notice both answers equal 85,382,255
With that explanation out of the way, let's continue. Next, we take the number 85,382,255 and divide it by 2:
85,382,255 ÷ 2 = 42,691,127.5
If the quotient is a whole number, then 2 and 42,691,127.5 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 | 85,382,255 | |
| -1 | -85,382,255 |
Now, we try dividing 85,382,255 by 3:
85,382,255 ÷ 3 = 28,460,751.6667
If the quotient is a whole number, then 3 and 28,460,751.6667 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 | 85,382,255 | |
| -1 | -85,382,255 |
Let's try dividing by 4:
85,382,255 ÷ 4 = 21,345,563.75
If the quotient is a whole number, then 4 and 21,345,563.75 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 | 85,382,255 | |
| -1 | 85,382,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 107 | 245 | 535 | 749 | 3,257 | 3,745 | 5,243 | 16,285 | 22,799 | 26,215 | 113,995 | 159,593 | 348,499 | 797,965 | 1,742,495 | 2,439,493 | 12,197,465 | 17,076,451 | 85,382,255 |
| -1 | -5 | -7 | -35 | -49 | -107 | -245 | -535 | -749 | -3,257 | -3,745 | -5,243 | -16,285 | -22,799 | -26,215 | -113,995 | -159,593 | -348,499 | -797,965 | -1,742,495 | -2,439,493 | -12,197,465 | -17,076,451 | -85,382,255 |
