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 89,817,553, 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 | 89,817,553 | |
| -1 | -89,817,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 89,817,553.
Example:
1 x 89,817,553 = 89,817,553
and
-1 x -89,817,553 = 89,817,553
Notice both answers equal 89,817,553
With that explanation out of the way, let's continue. Next, we take the number 89,817,553 and divide it by 2:
89,817,553 ÷ 2 = 44,908,776.5
If the quotient is a whole number, then 2 and 44,908,776.5 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 | 89,817,553 | |
| -1 | -89,817,553 |
Now, we try dividing 89,817,553 by 3:
89,817,553 ÷ 3 = 29,939,184.3333
If the quotient is a whole number, then 3 and 29,939,184.3333 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 | 89,817,553 | |
| -1 | -89,817,553 |
Let's try dividing by 4:
89,817,553 ÷ 4 = 22,454,388.25
If the quotient is a whole number, then 4 and 22,454,388.25 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 | 89,817,553 | |
| -1 | 89,817,553 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 29 | 161 | 203 | 667 | 4,669 | 19,237 | 134,659 | 442,451 | 557,873 | 3,097,157 | 3,905,111 | 12,831,079 | 89,817,553 |
| -1 | -7 | -23 | -29 | -161 | -203 | -667 | -4,669 | -19,237 | -134,659 | -442,451 | -557,873 | -3,097,157 | -3,905,111 | -12,831,079 | -89,817,553 |
