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 75,195,691, 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 | 75,195,691 | |
-1 | -75,195,691 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,195,691.
Example:
1 x 75,195,691 = 75,195,691
and
-1 x -75,195,691 = 75,195,691
Notice both answers equal 75,195,691
With that explanation out of the way, let's continue. Next, we take the number 75,195,691 and divide it by 2:
75,195,691 ÷ 2 = 37,597,845.5
If the quotient is a whole number, then 2 and 37,597,845.5 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 | 75,195,691 | |
-1 | -75,195,691 |
Now, we try dividing 75,195,691 by 3:
75,195,691 ÷ 3 = 25,065,230.3333
If the quotient is a whole number, then 3 and 25,065,230.3333 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 | 75,195,691 | |
-1 | -75,195,691 |
Let's try dividing by 4:
75,195,691 ÷ 4 = 18,798,922.75
If the quotient is a whole number, then 4 and 18,798,922.75 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 | 75,195,691 | |
-1 | 75,195,691 |
If you did it right, you will end up with this table:
1 | 43 | 1,748,737 | 75,195,691 |
-1 | -43 | -1,748,737 | -75,195,691 |
