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 42,103,523, 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 | 42,103,523 | |
| -1 | -42,103,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,103,523.
Example:
1 x 42,103,523 = 42,103,523
and
-1 x -42,103,523 = 42,103,523
Notice both answers equal 42,103,523
With that explanation out of the way, let's continue. Next, we take the number 42,103,523 and divide it by 2:
42,103,523 ÷ 2 = 21,051,761.5
If the quotient is a whole number, then 2 and 21,051,761.5 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 | 42,103,523 | |
| -1 | -42,103,523 |
Now, we try dividing 42,103,523 by 3:
42,103,523 ÷ 3 = 14,034,507.6667
If the quotient is a whole number, then 3 and 14,034,507.6667 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 | 42,103,523 | |
| -1 | -42,103,523 |
Let's try dividing by 4:
42,103,523 ÷ 4 = 10,525,880.75
If the quotient is a whole number, then 4 and 10,525,880.75 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 | 42,103,523 | |
| -1 | 42,103,523 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 121 | 847 | 1,331 | 4,519 | 9,317 | 31,633 | 49,709 | 347,963 | 546,799 | 3,827,593 | 6,014,789 | 42,103,523 |
| -1 | -7 | -11 | -77 | -121 | -847 | -1,331 | -4,519 | -9,317 | -31,633 | -49,709 | -347,963 | -546,799 | -3,827,593 | -6,014,789 | -42,103,523 |
