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 155,250,113, 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 | 155,250,113 | |
-1 | -155,250,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 155,250,113.
Example:
1 x 155,250,113 = 155,250,113
and
-1 x -155,250,113 = 155,250,113
Notice both answers equal 155,250,113
With that explanation out of the way, let's continue. Next, we take the number 155,250,113 and divide it by 2:
155,250,113 ÷ 2 = 77,625,056.5
If the quotient is a whole number, then 2 and 77,625,056.5 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 | 155,250,113 | |
-1 | -155,250,113 |
Now, we try dividing 155,250,113 by 3:
155,250,113 ÷ 3 = 51,750,037.6667
If the quotient is a whole number, then 3 and 51,750,037.6667 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 | 155,250,113 | |
-1 | -155,250,113 |
Let's try dividing by 4:
155,250,113 ÷ 4 = 38,812,528.25
If the quotient is a whole number, then 4 and 38,812,528.25 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 | 155,250,113 | |
-1 | 155,250,113 |
If you did it right, you will end up with this table:
1 | 37 | 4,195,949 | 155,250,113 |
-1 | -37 | -4,195,949 | -155,250,113 |
