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 85,813,283, 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 | 85,813,283 | |
-1 | -85,813,283 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 85,813,283.
Example:
1 x 85,813,283 = 85,813,283
and
-1 x -85,813,283 = 85,813,283
Notice both answers equal 85,813,283
With that explanation out of the way, let's continue. Next, we take the number 85,813,283 and divide it by 2:
85,813,283 ÷ 2 = 42,906,641.5
If the quotient is a whole number, then 2 and 42,906,641.5 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 | 85,813,283 | |
-1 | -85,813,283 |
Now, we try dividing 85,813,283 by 3:
85,813,283 ÷ 3 = 28,604,427.6667
If the quotient is a whole number, then 3 and 28,604,427.6667 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 | 85,813,283 | |
-1 | -85,813,283 |
Let's try dividing by 4:
85,813,283 ÷ 4 = 21,453,320.75
If the quotient is a whole number, then 4 and 21,453,320.75 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 | 85,813,283 | |
-1 | 85,813,283 |
If you did it right, you will end up with this table:
1 | 1,487 | 57,709 | 85,813,283 |
-1 | -1,487 | -57,709 | -85,813,283 |
