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 142,520,443, 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 | 142,520,443 | |
| -1 | -142,520,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,520,443.
Example:
1 x 142,520,443 = 142,520,443
and
-1 x -142,520,443 = 142,520,443
Notice both answers equal 142,520,443
With that explanation out of the way, let's continue. Next, we take the number 142,520,443 and divide it by 2:
142,520,443 ÷ 2 = 71,260,221.5
If the quotient is a whole number, then 2 and 71,260,221.5 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 | 142,520,443 | |
| -1 | -142,520,443 |
Now, we try dividing 142,520,443 by 3:
142,520,443 ÷ 3 = 47,506,814.3333
If the quotient is a whole number, then 3 and 47,506,814.3333 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 | 142,520,443 | |
| -1 | -142,520,443 |
Let's try dividing by 4:
142,520,443 ÷ 4 = 35,630,110.75
If the quotient is a whole number, then 4 and 35,630,110.75 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 | 142,520,443 | |
| -1 | 142,520,443 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 109 | 299 | 1,417 | 2,507 | 4,373 | 32,591 | 56,849 | 100,579 | 476,657 | 1,307,527 | 6,196,541 | 10,963,111 | 142,520,443 |
| -1 | -13 | -23 | -109 | -299 | -1,417 | -2,507 | -4,373 | -32,591 | -56,849 | -100,579 | -476,657 | -1,307,527 | -6,196,541 | -10,963,111 | -142,520,443 |
