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 142,201,111, 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 | 142,201,111 | |
| -1 | -142,201,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,201,111.
Example:
1 x 142,201,111 = 142,201,111
and
-1 x -142,201,111 = 142,201,111
Notice both answers equal 142,201,111
With that explanation out of the way, let's continue. Next, we take the number 142,201,111 and divide it by 2:
142,201,111 ÷ 2 = 71,100,555.5
If the quotient is a whole number, then 2 and 71,100,555.5 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 | 142,201,111 | |
| -1 | -142,201,111 |
Now, we try dividing 142,201,111 by 3:
142,201,111 ÷ 3 = 47,400,370.3333
If the quotient is a whole number, then 3 and 47,400,370.3333 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 | 142,201,111 | |
| -1 | -142,201,111 |
Let's try dividing by 4:
142,201,111 ÷ 4 = 35,550,277.75
If the quotient is a whole number, then 4 and 35,550,277.75 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 | 142,201,111 | |
| -1 | 142,201,111 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 23 | 247 | 299 | 437 | 5,681 | 25,031 | 325,403 | 475,589 | 575,713 | 6,182,657 | 7,484,269 | 10,938,547 | 142,201,111 |
| -1 | -13 | -19 | -23 | -247 | -299 | -437 | -5,681 | -25,031 | -325,403 | -475,589 | -575,713 | -6,182,657 | -7,484,269 | -10,938,547 | -142,201,111 |
