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 1,867,445, 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 | 1,867,445 | |
-1 | -1,867,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,867,445.
Example:
1 x 1,867,445 = 1,867,445
and
-1 x -1,867,445 = 1,867,445
Notice both answers equal 1,867,445
With that explanation out of the way, let's continue. Next, we take the number 1,867,445 and divide it by 2:
1,867,445 ÷ 2 = 933,722.5
If the quotient is a whole number, then 2 and 933,722.5 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 | 1,867,445 | |
-1 | -1,867,445 |
Now, we try dividing 1,867,445 by 3:
1,867,445 ÷ 3 = 622,481.6667
If the quotient is a whole number, then 3 and 622,481.6667 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 | 1,867,445 | |
-1 | -1,867,445 |
Let's try dividing by 4:
1,867,445 ÷ 4 = 466,861.25
If the quotient is a whole number, then 4 and 466,861.25 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 | 1,867,445 | |
-1 | 1,867,445 |
If you did it right, you will end up with this table:
1 | 5 | 373,489 | 1,867,445 |
-1 | -5 | -373,489 | -1,867,445 |
