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 2,985,325, 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 | 2,985,325 | |
| -1 | -2,985,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,985,325.
Example:
1 x 2,985,325 = 2,985,325
and
-1 x -2,985,325 = 2,985,325
Notice both answers equal 2,985,325
With that explanation out of the way, let's continue. Next, we take the number 2,985,325 and divide it by 2:
2,985,325 ÷ 2 = 1,492,662.5
If the quotient is a whole number, then 2 and 1,492,662.5 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 | 2,985,325 | |
| -1 | -2,985,325 |
Now, we try dividing 2,985,325 by 3:
2,985,325 ÷ 3 = 995,108.3333
If the quotient is a whole number, then 3 and 995,108.3333 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 | 2,985,325 | |
| -1 | -2,985,325 |
Let's try dividing by 4:
2,985,325 ÷ 4 = 746,331.25
If the quotient is a whole number, then 4 and 746,331.25 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 | 2,985,325 | |
| -1 | 2,985,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 2,437 | 12,185 | 17,059 | 60,925 | 85,295 | 119,413 | 426,475 | 597,065 | 2,985,325 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -2,437 | -12,185 | -17,059 | -60,925 | -85,295 | -119,413 | -426,475 | -597,065 | -2,985,325 |
