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 375,725,221, 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 | 375,725,221 | |
-1 | -375,725,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 375,725,221.
Example:
1 x 375,725,221 = 375,725,221
and
-1 x -375,725,221 = 375,725,221
Notice both answers equal 375,725,221
With that explanation out of the way, let's continue. Next, we take the number 375,725,221 and divide it by 2:
375,725,221 ÷ 2 = 187,862,610.5
If the quotient is a whole number, then 2 and 187,862,610.5 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 | 375,725,221 | |
-1 | -375,725,221 |
Now, we try dividing 375,725,221 by 3:
375,725,221 ÷ 3 = 125,241,740.3333
If the quotient is a whole number, then 3 and 125,241,740.3333 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 | 375,725,221 | |
-1 | -375,725,221 |
Let's try dividing by 4:
375,725,221 ÷ 4 = 93,931,305.25
If the quotient is a whole number, then 4 and 93,931,305.25 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 | 375,725,221 | |
-1 | 375,725,221 |
If you did it right, you will end up with this table:
1 | 3,049 | 123,229 | 375,725,221 |
-1 | -3,049 | -123,229 | -375,725,221 |
