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 5,144,557, 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 | 5,144,557 | |
| -1 | -5,144,557 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,144,557.
Example:
1 x 5,144,557 = 5,144,557
and
-1 x -5,144,557 = 5,144,557
Notice both answers equal 5,144,557
With that explanation out of the way, let's continue. Next, we take the number 5,144,557 and divide it by 2:
5,144,557 ÷ 2 = 2,572,278.5
If the quotient is a whole number, then 2 and 2,572,278.5 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 | 5,144,557 | |
| -1 | -5,144,557 |
Now, we try dividing 5,144,557 by 3:
5,144,557 ÷ 3 = 1,714,852.3333
If the quotient is a whole number, then 3 and 1,714,852.3333 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 | 5,144,557 | |
| -1 | -5,144,557 |
Let's try dividing by 4:
5,144,557 ÷ 4 = 1,286,139.25
If the quotient is a whole number, then 4 and 1,286,139.25 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 | 5,144,557 | |
| -1 | 5,144,557 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 41 | 61 | 121 | 187 | 451 | 671 | 697 | 1,037 | 2,057 | 2,501 | 4,961 | 7,381 | 7,667 | 11,407 | 27,511 | 42,517 | 84,337 | 125,477 | 302,621 | 467,687 | 5,144,557 |
| -1 | -11 | -17 | -41 | -61 | -121 | -187 | -451 | -671 | -697 | -1,037 | -2,057 | -2,501 | -4,961 | -7,381 | -7,667 | -11,407 | -27,511 | -42,517 | -84,337 | -125,477 | -302,621 | -467,687 | -5,144,557 |
