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 143,341,121, 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 | 143,341,121 | |
| -1 | -143,341,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,341,121.
Example:
1 x 143,341,121 = 143,341,121
and
-1 x -143,341,121 = 143,341,121
Notice both answers equal 143,341,121
With that explanation out of the way, let's continue. Next, we take the number 143,341,121 and divide it by 2:
143,341,121 ÷ 2 = 71,670,560.5
If the quotient is a whole number, then 2 and 71,670,560.5 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 | 143,341,121 | |
| -1 | -143,341,121 |
Now, we try dividing 143,341,121 by 3:
143,341,121 ÷ 3 = 47,780,373.6667
If the quotient is a whole number, then 3 and 47,780,373.6667 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 | 143,341,121 | |
| -1 | -143,341,121 |
Let's try dividing by 4:
143,341,121 ÷ 4 = 35,835,280.25
If the quotient is a whole number, then 4 and 35,835,280.25 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 | 143,341,121 | |
| -1 | 143,341,121 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 73 | 77 | 511 | 539 | 803 | 3,577 | 3,643 | 5,621 | 25,501 | 39,347 | 40,073 | 178,507 | 265,939 | 280,511 | 1,861,573 | 1,963,577 | 2,925,329 | 13,031,011 | 20,477,303 | 143,341,121 |
| -1 | -7 | -11 | -49 | -73 | -77 | -511 | -539 | -803 | -3,577 | -3,643 | -5,621 | -25,501 | -39,347 | -40,073 | -178,507 | -265,939 | -280,511 | -1,861,573 | -1,963,577 | -2,925,329 | -13,031,011 | -20,477,303 | -143,341,121 |
