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 67,502,245, 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 | 67,502,245 | |
| -1 | -67,502,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,502,245.
Example:
1 x 67,502,245 = 67,502,245
and
-1 x -67,502,245 = 67,502,245
Notice both answers equal 67,502,245
With that explanation out of the way, let's continue. Next, we take the number 67,502,245 and divide it by 2:
67,502,245 ÷ 2 = 33,751,122.5
If the quotient is a whole number, then 2 and 33,751,122.5 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 | 67,502,245 | |
| -1 | -67,502,245 |
Now, we try dividing 67,502,245 by 3:
67,502,245 ÷ 3 = 22,500,748.3333
If the quotient is a whole number, then 3 and 22,500,748.3333 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 | 67,502,245 | |
| -1 | -67,502,245 |
Let's try dividing by 4:
67,502,245 ÷ 4 = 16,875,561.25
If the quotient is a whole number, then 4 and 16,875,561.25 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 | 67,502,245 | |
| -1 | 67,502,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 113 | 185 | 565 | 3,229 | 4,181 | 16,145 | 20,905 | 119,473 | 364,877 | 597,365 | 1,824,385 | 13,500,449 | 67,502,245 |
| -1 | -5 | -37 | -113 | -185 | -565 | -3,229 | -4,181 | -16,145 | -20,905 | -119,473 | -364,877 | -597,365 | -1,824,385 | -13,500,449 | -67,502,245 |
