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 1,257,635, 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 | 1,257,635 | |
-1 | -1,257,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,257,635.
Example:
1 x 1,257,635 = 1,257,635
and
-1 x -1,257,635 = 1,257,635
Notice both answers equal 1,257,635
With that explanation out of the way, let's continue. Next, we take the number 1,257,635 and divide it by 2:
1,257,635 ÷ 2 = 628,817.5
If the quotient is a whole number, then 2 and 628,817.5 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 | 1,257,635 | |
-1 | -1,257,635 |
Now, we try dividing 1,257,635 by 3:
1,257,635 ÷ 3 = 419,211.6667
If the quotient is a whole number, then 3 and 419,211.6667 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 | 1,257,635 | |
-1 | -1,257,635 |
Let's try dividing by 4:
1,257,635 ÷ 4 = 314,408.75
If the quotient is a whole number, then 4 and 314,408.75 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 | 1,257,635 | |
-1 | 1,257,635 |
If you did it right, you will end up with this table:
1 | 5 | 251,527 | 1,257,635 |
-1 | -5 | -251,527 | -1,257,635 |
