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 1,975,171, 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 | 1,975,171 | |
| -1 | -1,975,171 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,975,171.
Example:
1 x 1,975,171 = 1,975,171
and
-1 x -1,975,171 = 1,975,171
Notice both answers equal 1,975,171
With that explanation out of the way, let's continue. Next, we take the number 1,975,171 and divide it by 2:
1,975,171 ÷ 2 = 987,585.5
If the quotient is a whole number, then 2 and 987,585.5 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 | 1,975,171 | |
| -1 | -1,975,171 |
Now, we try dividing 1,975,171 by 3:
1,975,171 ÷ 3 = 658,390.3333
If the quotient is a whole number, then 3 and 658,390.3333 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 | 1,975,171 | |
| -1 | -1,975,171 |
Let's try dividing by 4:
1,975,171 ÷ 4 = 493,792.75
If the quotient is a whole number, then 4 and 493,792.75 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 | 1,975,171 | |
| -1 | 1,975,171 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 37 | 211 | 253 | 407 | 851 | 2,321 | 4,853 | 7,807 | 9,361 | 53,383 | 85,877 | 179,561 | 1,975,171 |
| -1 | -11 | -23 | -37 | -211 | -253 | -407 | -851 | -2,321 | -4,853 | -7,807 | -9,361 | -53,383 | -85,877 | -179,561 | -1,975,171 |
