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 142,434,145, 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 | 142,434,145 | |
| -1 | -142,434,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,434,145.
Example:
1 x 142,434,145 = 142,434,145
and
-1 x -142,434,145 = 142,434,145
Notice both answers equal 142,434,145
With that explanation out of the way, let's continue. Next, we take the number 142,434,145 and divide it by 2:
142,434,145 ÷ 2 = 71,217,072.5
If the quotient is a whole number, then 2 and 71,217,072.5 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 | 142,434,145 | |
| -1 | -142,434,145 |
Now, we try dividing 142,434,145 by 3:
142,434,145 ÷ 3 = 47,478,048.3333
If the quotient is a whole number, then 3 and 47,478,048.3333 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 | 142,434,145 | |
| -1 | -142,434,145 |
Let's try dividing by 4:
142,434,145 ÷ 4 = 35,608,536.25
If the quotient is a whole number, then 4 and 35,608,536.25 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 | 142,434,145 | |
| -1 | 142,434,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 643 | 3,215 | 4,501 | 6,329 | 22,505 | 31,645 | 44,303 | 221,515 | 4,069,547 | 20,347,735 | 28,486,829 | 142,434,145 |
| -1 | -5 | -7 | -35 | -643 | -3,215 | -4,501 | -6,329 | -22,505 | -31,645 | -44,303 | -221,515 | -4,069,547 | -20,347,735 | -28,486,829 | -142,434,145 |
