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 89,221,777, 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 | 89,221,777 | |
| -1 | -89,221,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 89,221,777.
Example:
1 x 89,221,777 = 89,221,777
and
-1 x -89,221,777 = 89,221,777
Notice both answers equal 89,221,777
With that explanation out of the way, let's continue. Next, we take the number 89,221,777 and divide it by 2:
89,221,777 ÷ 2 = 44,610,888.5
If the quotient is a whole number, then 2 and 44,610,888.5 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 | 89,221,777 | |
| -1 | -89,221,777 |
Now, we try dividing 89,221,777 by 3:
89,221,777 ÷ 3 = 29,740,592.3333
If the quotient is a whole number, then 3 and 29,740,592.3333 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 | 89,221,777 | |
| -1 | -89,221,777 |
Let's try dividing by 4:
89,221,777 ÷ 4 = 22,305,444.25
If the quotient is a whole number, then 4 and 22,305,444.25 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 | 89,221,777 | |
| -1 | 89,221,777 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 193 | 551 | 839 | 3,667 | 5,597 | 15,941 | 24,331 | 106,343 | 161,927 | 462,289 | 3,076,613 | 4,695,883 | 89,221,777 |
| -1 | -19 | -29 | -193 | -551 | -839 | -3,667 | -5,597 | -15,941 | -24,331 | -106,343 | -161,927 | -462,289 | -3,076,613 | -4,695,883 | -89,221,777 |
