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 90,457,345, 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 | 90,457,345 | |
| -1 | -90,457,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 90,457,345.
Example:
1 x 90,457,345 = 90,457,345
and
-1 x -90,457,345 = 90,457,345
Notice both answers equal 90,457,345
With that explanation out of the way, let's continue. Next, we take the number 90,457,345 and divide it by 2:
90,457,345 ÷ 2 = 45,228,672.5
If the quotient is a whole number, then 2 and 45,228,672.5 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 | 90,457,345 | |
| -1 | -90,457,345 |
Now, we try dividing 90,457,345 by 3:
90,457,345 ÷ 3 = 30,152,448.3333
If the quotient is a whole number, then 3 and 30,152,448.3333 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 | 90,457,345 | |
| -1 | -90,457,345 |
Let's try dividing by 4:
90,457,345 ÷ 4 = 22,614,336.25
If the quotient is a whole number, then 4 and 22,614,336.25 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 | 90,457,345 | |
| -1 | 90,457,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 613 | 2,683 | 3,065 | 6,743 | 13,415 | 29,513 | 33,715 | 147,565 | 1,644,679 | 8,223,395 | 18,091,469 | 90,457,345 |
| -1 | -5 | -11 | -55 | -613 | -2,683 | -3,065 | -6,743 | -13,415 | -29,513 | -33,715 | -147,565 | -1,644,679 | -8,223,395 | -18,091,469 | -90,457,345 |
