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 40,670,245, 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 | 40,670,245 | |
| -1 | -40,670,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,670,245.
Example:
1 x 40,670,245 = 40,670,245
and
-1 x -40,670,245 = 40,670,245
Notice both answers equal 40,670,245
With that explanation out of the way, let's continue. Next, we take the number 40,670,245 and divide it by 2:
40,670,245 ÷ 2 = 20,335,122.5
If the quotient is a whole number, then 2 and 20,335,122.5 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 | 40,670,245 | |
| -1 | -40,670,245 |
Now, we try dividing 40,670,245 by 3:
40,670,245 ÷ 3 = 13,556,748.3333
If the quotient is a whole number, then 3 and 13,556,748.3333 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 | 40,670,245 | |
| -1 | -40,670,245 |
Let's try dividing by 4:
40,670,245 ÷ 4 = 10,167,561.25
If the quotient is a whole number, then 4 and 10,167,561.25 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 | 40,670,245 | |
| -1 | 40,670,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 245 | 385 | 539 | 2,695 | 15,091 | 75,455 | 105,637 | 166,001 | 528,185 | 739,459 | 830,005 | 1,162,007 | 3,697,295 | 5,810,035 | 8,134,049 | 40,670,245 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -245 | -385 | -539 | -2,695 | -15,091 | -75,455 | -105,637 | -166,001 | -528,185 | -739,459 | -830,005 | -1,162,007 | -3,697,295 | -5,810,035 | -8,134,049 | -40,670,245 |
