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 42,474,041, 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 | 42,474,041 | |
| -1 | -42,474,041 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,474,041.
Example:
1 x 42,474,041 = 42,474,041
and
-1 x -42,474,041 = 42,474,041
Notice both answers equal 42,474,041
With that explanation out of the way, let's continue. Next, we take the number 42,474,041 and divide it by 2:
42,474,041 ÷ 2 = 21,237,020.5
If the quotient is a whole number, then 2 and 21,237,020.5 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 | 42,474,041 | |
| -1 | -42,474,041 |
Now, we try dividing 42,474,041 by 3:
42,474,041 ÷ 3 = 14,158,013.6667
If the quotient is a whole number, then 3 and 14,158,013.6667 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 | 42,474,041 | |
| -1 | -42,474,041 |
Let's try dividing by 4:
42,474,041 ÷ 4 = 10,618,510.25
If the quotient is a whole number, then 4 and 10,618,510.25 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 | 42,474,041 | |
| -1 | 42,474,041 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 53 | 59 | 289 | 799 | 901 | 1,003 | 2,491 | 2,773 | 3,127 | 13,583 | 15,317 | 17,051 | 42,347 | 47,141 | 53,159 | 146,969 | 719,899 | 801,397 | 903,703 | 2,498,473 | 42,474,041 |
| -1 | -17 | -47 | -53 | -59 | -289 | -799 | -901 | -1,003 | -2,491 | -2,773 | -3,127 | -13,583 | -15,317 | -17,051 | -42,347 | -47,141 | -53,159 | -146,969 | -719,899 | -801,397 | -903,703 | -2,498,473 | -42,474,041 |
