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 161,895,863, 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 | 161,895,863 | |
-1 | -161,895,863 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 161,895,863.
Example:
1 x 161,895,863 = 161,895,863
and
-1 x -161,895,863 = 161,895,863
Notice both answers equal 161,895,863
With that explanation out of the way, let's continue. Next, we take the number 161,895,863 and divide it by 2:
161,895,863 ÷ 2 = 80,947,931.5
If the quotient is a whole number, then 2 and 80,947,931.5 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 | 161,895,863 | |
-1 | -161,895,863 |
Now, we try dividing 161,895,863 by 3:
161,895,863 ÷ 3 = 53,965,287.6667
If the quotient is a whole number, then 3 and 53,965,287.6667 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 | 161,895,863 | |
-1 | -161,895,863 |
Let's try dividing by 4:
161,895,863 ÷ 4 = 40,473,965.75
If the quotient is a whole number, then 4 and 40,473,965.75 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 | 161,895,863 | |
-1 | 161,895,863 |
If you did it right, you will end up with this table:
1 | 569 | 284,527 | 161,895,863 |
-1 | -569 | -284,527 | -161,895,863 |
