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 143,154,011, 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 | 143,154,011 | |
| -1 | -143,154,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,154,011.
Example:
1 x 143,154,011 = 143,154,011
and
-1 x -143,154,011 = 143,154,011
Notice both answers equal 143,154,011
With that explanation out of the way, let's continue. Next, we take the number 143,154,011 and divide it by 2:
143,154,011 ÷ 2 = 71,577,005.5
If the quotient is a whole number, then 2 and 71,577,005.5 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 | 143,154,011 | |
| -1 | -143,154,011 |
Now, we try dividing 143,154,011 by 3:
143,154,011 ÷ 3 = 47,718,003.6667
If the quotient is a whole number, then 3 and 47,718,003.6667 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 | 143,154,011 | |
| -1 | -143,154,011 |
Let's try dividing by 4:
143,154,011 ÷ 4 = 35,788,502.75
If the quotient is a whole number, then 4 and 35,788,502.75 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 | 143,154,011 | |
| -1 | 143,154,011 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 121 | 143 | 847 | 1,001 | 1,573 | 11,011 | 13,001 | 91,007 | 143,011 | 169,013 | 1,001,077 | 1,183,091 | 1,573,121 | 1,859,143 | 11,011,847 | 13,014,001 | 20,450,573 | 143,154,011 |
| -1 | -7 | -11 | -13 | -77 | -91 | -121 | -143 | -847 | -1,001 | -1,573 | -11,011 | -13,001 | -91,007 | -143,011 | -169,013 | -1,001,077 | -1,183,091 | -1,573,121 | -1,859,143 | -11,011,847 | -13,014,001 | -20,450,573 | -143,154,011 |
