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 4,975,475, 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 | 4,975,475 | |
| -1 | -4,975,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,975,475.
Example:
1 x 4,975,475 = 4,975,475
and
-1 x -4,975,475 = 4,975,475
Notice both answers equal 4,975,475
With that explanation out of the way, let's continue. Next, we take the number 4,975,475 and divide it by 2:
4,975,475 ÷ 2 = 2,487,737.5
If the quotient is a whole number, then 2 and 2,487,737.5 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 | 4,975,475 | |
| -1 | -4,975,475 |
Now, we try dividing 4,975,475 by 3:
4,975,475 ÷ 3 = 1,658,491.6667
If the quotient is a whole number, then 3 and 1,658,491.6667 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 | 4,975,475 | |
| -1 | -4,975,475 |
Let's try dividing by 4:
4,975,475 ÷ 4 = 1,243,868.75
If the quotient is a whole number, then 4 and 1,243,868.75 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 | 4,975,475 | |
| -1 | 4,975,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 25 | 85 | 115 | 391 | 425 | 509 | 575 | 1,955 | 2,545 | 8,653 | 9,775 | 11,707 | 12,725 | 43,265 | 58,535 | 199,019 | 216,325 | 292,675 | 995,095 | 4,975,475 |
| -1 | -5 | -17 | -23 | -25 | -85 | -115 | -391 | -425 | -509 | -575 | -1,955 | -2,545 | -8,653 | -9,775 | -11,707 | -12,725 | -43,265 | -58,535 | -199,019 | -216,325 | -292,675 | -995,095 | -4,975,475 |
