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 371,977, 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 | 371,977 | |
-1 | -371,977 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 371,977.
Example:
1 x 371,977 = 371,977
and
-1 x -371,977 = 371,977
Notice both answers equal 371,977
With that explanation out of the way, let's continue. Next, we take the number 371,977 and divide it by 2:
371,977 ÷ 2 = 185,988.5
If the quotient is a whole number, then 2 and 185,988.5 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 | 371,977 | |
-1 | -371,977 |
Now, we try dividing 371,977 by 3:
371,977 ÷ 3 = 123,992.3333
If the quotient is a whole number, then 3 and 123,992.3333 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 | 371,977 | |
-1 | -371,977 |
Let's try dividing by 4:
371,977 ÷ 4 = 92,994.25
If the quotient is a whole number, then 4 and 92,994.25 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 | 371,977 | |
-1 | 371,977 |
If you did it right, you will end up with this table:
1 | 17 | 21,881 | 371,977 |
-1 | -17 | -21,881 | -371,977 |
