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 85,466,275, 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 | 85,466,275 | |
| -1 | -85,466,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 85,466,275.
Example:
1 x 85,466,275 = 85,466,275
and
-1 x -85,466,275 = 85,466,275
Notice both answers equal 85,466,275
With that explanation out of the way, let's continue. Next, we take the number 85,466,275 and divide it by 2:
85,466,275 ÷ 2 = 42,733,137.5
If the quotient is a whole number, then 2 and 42,733,137.5 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 | 85,466,275 | |
| -1 | -85,466,275 |
Now, we try dividing 85,466,275 by 3:
85,466,275 ÷ 3 = 28,488,758.3333
If the quotient is a whole number, then 3 and 28,488,758.3333 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 | 85,466,275 | |
| -1 | -85,466,275 |
Let's try dividing by 4:
85,466,275 ÷ 4 = 21,366,568.75
If the quotient is a whole number, then 4 and 21,366,568.75 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 | 85,466,275 | |
| -1 | 85,466,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 25 | 95 | 115 | 437 | 475 | 575 | 2,185 | 7,823 | 10,925 | 39,115 | 148,637 | 179,929 | 195,575 | 743,185 | 899,645 | 3,418,651 | 3,715,925 | 4,498,225 | 17,093,255 | 85,466,275 |
| -1 | -5 | -19 | -23 | -25 | -95 | -115 | -437 | -475 | -575 | -2,185 | -7,823 | -10,925 | -39,115 | -148,637 | -179,929 | -195,575 | -743,185 | -899,645 | -3,418,651 | -3,715,925 | -4,498,225 | -17,093,255 | -85,466,275 |
