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 4,172,077, 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 | 4,172,077 | |
| -1 | -4,172,077 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,172,077.
Example:
1 x 4,172,077 = 4,172,077
and
-1 x -4,172,077 = 4,172,077
Notice both answers equal 4,172,077
With that explanation out of the way, let's continue. Next, we take the number 4,172,077 and divide it by 2:
4,172,077 ÷ 2 = 2,086,038.5
If the quotient is a whole number, then 2 and 2,086,038.5 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 | 4,172,077 | |
| -1 | -4,172,077 |
Now, we try dividing 4,172,077 by 3:
4,172,077 ÷ 3 = 1,390,692.3333
If the quotient is a whole number, then 3 and 1,390,692.3333 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 | 4,172,077 | |
| -1 | -4,172,077 |
Let's try dividing by 4:
4,172,077 ÷ 4 = 1,043,019.25
If the quotient is a whole number, then 4 and 1,043,019.25 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 | 4,172,077 | |
| -1 | 4,172,077 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 91 | 127 | 133 | 247 | 361 | 889 | 1,651 | 1,729 | 2,413 | 2,527 | 4,693 | 11,557 | 16,891 | 31,369 | 32,851 | 45,847 | 219,583 | 320,929 | 596,011 | 4,172,077 |
| -1 | -7 | -13 | -19 | -91 | -127 | -133 | -247 | -361 | -889 | -1,651 | -1,729 | -2,413 | -2,527 | -4,693 | -11,557 | -16,891 | -31,369 | -32,851 | -45,847 | -219,583 | -320,929 | -596,011 | -4,172,077 |
