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 42,536,431, 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 | 42,536,431 | |
| -1 | -42,536,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,536,431.
Example:
1 x 42,536,431 = 42,536,431
and
-1 x -42,536,431 = 42,536,431
Notice both answers equal 42,536,431
With that explanation out of the way, let's continue. Next, we take the number 42,536,431 and divide it by 2:
42,536,431 ÷ 2 = 21,268,215.5
If the quotient is a whole number, then 2 and 21,268,215.5 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 | 42,536,431 | |
| -1 | -42,536,431 |
Now, we try dividing 42,536,431 by 3:
42,536,431 ÷ 3 = 14,178,810.3333
If the quotient is a whole number, then 3 and 14,178,810.3333 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 | 42,536,431 | |
| -1 | -42,536,431 |
Let's try dividing by 4:
42,536,431 ÷ 4 = 10,634,107.75
If the quotient is a whole number, then 4 and 10,634,107.75 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 | 42,536,431 | |
| -1 | 42,536,431 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 271 | 1,319 | 1,897 | 4,607 | 9,233 | 22,423 | 32,249 | 156,961 | 357,449 | 2,502,143 | 6,076,633 | 42,536,431 |
| -1 | -7 | -17 | -119 | -271 | -1,319 | -1,897 | -4,607 | -9,233 | -22,423 | -32,249 | -156,961 | -357,449 | -2,502,143 | -6,076,633 | -42,536,431 |
