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 142,431,541, 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 | 142,431,541 | |
| -1 | -142,431,541 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,431,541.
Example:
1 x 142,431,541 = 142,431,541
and
-1 x -142,431,541 = 142,431,541
Notice both answers equal 142,431,541
With that explanation out of the way, let's continue. Next, we take the number 142,431,541 and divide it by 2:
142,431,541 ÷ 2 = 71,215,770.5
If the quotient is a whole number, then 2 and 71,215,770.5 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 | 142,431,541 | |
| -1 | -142,431,541 |
Now, we try dividing 142,431,541 by 3:
142,431,541 ÷ 3 = 47,477,180.3333
If the quotient is a whole number, then 3 and 47,477,180.3333 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 | 142,431,541 | |
| -1 | -142,431,541 |
Let's try dividing by 4:
142,431,541 ÷ 4 = 35,607,885.25
If the quotient is a whole number, then 4 and 35,607,885.25 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 | 142,431,541 | |
| -1 | 142,431,541 |
If you did it right, you will end up with this table:
| 1 | 7 | 73 | 211 | 511 | 1,321 | 1,477 | 9,247 | 15,403 | 96,433 | 107,821 | 278,731 | 675,031 | 1,951,117 | 20,347,363 | 142,431,541 |
| -1 | -7 | -73 | -211 | -511 | -1,321 | -1,477 | -9,247 | -15,403 | -96,433 | -107,821 | -278,731 | -675,031 | -1,951,117 | -20,347,363 | -142,431,541 |
