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 45,238,427, 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 | 45,238,427 | |
| -1 | -45,238,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,238,427.
Example:
1 x 45,238,427 = 45,238,427
and
-1 x -45,238,427 = 45,238,427
Notice both answers equal 45,238,427
With that explanation out of the way, let's continue. Next, we take the number 45,238,427 and divide it by 2:
45,238,427 ÷ 2 = 22,619,213.5
If the quotient is a whole number, then 2 and 22,619,213.5 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 | 45,238,427 | |
| -1 | -45,238,427 |
Now, we try dividing 45,238,427 by 3:
45,238,427 ÷ 3 = 15,079,475.6667
If the quotient is a whole number, then 3 and 15,079,475.6667 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 | 45,238,427 | |
| -1 | -45,238,427 |
Let's try dividing by 4:
45,238,427 ÷ 4 = 11,309,606.75
If the quotient is a whole number, then 4 and 11,309,606.75 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 | 45,238,427 | |
| -1 | 45,238,427 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 169 | 349 | 767 | 2,197 | 4,537 | 9,971 | 20,591 | 58,981 | 129,623 | 267,683 | 766,753 | 3,479,879 | 45,238,427 |
| -1 | -13 | -59 | -169 | -349 | -767 | -2,197 | -4,537 | -9,971 | -20,591 | -58,981 | -129,623 | -267,683 | -766,753 | -3,479,879 | -45,238,427 |
