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 142,434,523, 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 | 142,434,523 | |
| -1 | -142,434,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,434,523.
Example:
1 x 142,434,523 = 142,434,523
and
-1 x -142,434,523 = 142,434,523
Notice both answers equal 142,434,523
With that explanation out of the way, let's continue. Next, we take the number 142,434,523 and divide it by 2:
142,434,523 ÷ 2 = 71,217,261.5
If the quotient is a whole number, then 2 and 71,217,261.5 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 | 142,434,523 | |
| -1 | -142,434,523 |
Now, we try dividing 142,434,523 by 3:
142,434,523 ÷ 3 = 47,478,174.3333
If the quotient is a whole number, then 3 and 47,478,174.3333 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 | 142,434,523 | |
| -1 | -142,434,523 |
Let's try dividing by 4:
142,434,523 ÷ 4 = 35,608,630.75
If the quotient is a whole number, then 4 and 35,608,630.75 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 | 142,434,523 | |
| -1 | 142,434,523 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 343 | 539 | 2,401 | 3,773 | 5,393 | 26,411 | 37,751 | 59,323 | 264,257 | 415,261 | 1,849,799 | 2,906,827 | 12,948,593 | 20,347,789 | 142,434,523 |
| -1 | -7 | -11 | -49 | -77 | -343 | -539 | -2,401 | -3,773 | -5,393 | -26,411 | -37,751 | -59,323 | -264,257 | -415,261 | -1,849,799 | -2,906,827 | -12,948,593 | -20,347,789 | -142,434,523 |
