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 7,578,251, 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 | 7,578,251 | |
-1 | -7,578,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,578,251.
Example:
1 x 7,578,251 = 7,578,251
and
-1 x -7,578,251 = 7,578,251
Notice both answers equal 7,578,251
With that explanation out of the way, let's continue. Next, we take the number 7,578,251 and divide it by 2:
7,578,251 ÷ 2 = 3,789,125.5
If the quotient is a whole number, then 2 and 3,789,125.5 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 | 7,578,251 | |
-1 | -7,578,251 |
Now, we try dividing 7,578,251 by 3:
7,578,251 ÷ 3 = 2,526,083.6667
If the quotient is a whole number, then 3 and 2,526,083.6667 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 | 7,578,251 | |
-1 | -7,578,251 |
Let's try dividing by 4:
7,578,251 ÷ 4 = 1,894,562.75
If the quotient is a whole number, then 4 and 1,894,562.75 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 | 7,578,251 | |
-1 | 7,578,251 |
If you did it right, you will end up with this table:
1 | 29 | 841 | 9,011 | 261,319 | 7,578,251 |
-1 | -29 | -841 | -9,011 | -261,319 | -7,578,251 |
