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 89,427,701, 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 | 89,427,701 | |
| -1 | -89,427,701 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 89,427,701.
Example:
1 x 89,427,701 = 89,427,701
and
-1 x -89,427,701 = 89,427,701
Notice both answers equal 89,427,701
With that explanation out of the way, let's continue. Next, we take the number 89,427,701 and divide it by 2:
89,427,701 ÷ 2 = 44,713,850.5
If the quotient is a whole number, then 2 and 44,713,850.5 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 | 89,427,701 | |
| -1 | -89,427,701 |
Now, we try dividing 89,427,701 by 3:
89,427,701 ÷ 3 = 29,809,233.6667
If the quotient is a whole number, then 3 and 29,809,233.6667 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 | 89,427,701 | |
| -1 | -89,427,701 |
Let's try dividing by 4:
89,427,701 ÷ 4 = 22,356,925.25
If the quotient is a whole number, then 4 and 22,356,925.25 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 | 89,427,701 | |
| -1 | 89,427,701 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 73 | 187 | 803 | 1,241 | 6,551 | 13,651 | 72,061 | 111,367 | 478,223 | 1,225,037 | 5,260,453 | 8,129,791 | 89,427,701 |
| -1 | -11 | -17 | -73 | -187 | -803 | -1,241 | -6,551 | -13,651 | -72,061 | -111,367 | -478,223 | -1,225,037 | -5,260,453 | -8,129,791 | -89,427,701 |
