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 143,146,211, 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 | 143,146,211 | |
| -1 | -143,146,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,146,211.
Example:
1 x 143,146,211 = 143,146,211
and
-1 x -143,146,211 = 143,146,211
Notice both answers equal 143,146,211
With that explanation out of the way, let's continue. Next, we take the number 143,146,211 and divide it by 2:
143,146,211 ÷ 2 = 71,573,105.5
If the quotient is a whole number, then 2 and 71,573,105.5 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 | 143,146,211 | |
| -1 | -143,146,211 |
Now, we try dividing 143,146,211 by 3:
143,146,211 ÷ 3 = 47,715,403.6667
If the quotient is a whole number, then 3 and 47,715,403.6667 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 | 143,146,211 | |
| -1 | -143,146,211 |
Let's try dividing by 4:
143,146,211 ÷ 4 = 35,786,552.75
If the quotient is a whole number, then 4 and 35,786,552.75 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 | 143,146,211 | |
| -1 | 143,146,211 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 73 | 169 | 283 | 533 | 949 | 2,993 | 3,679 | 6,929 | 11,603 | 12,337 | 20,659 | 38,909 | 47,827 | 150,839 | 268,567 | 505,817 | 847,019 | 1,960,907 | 3,491,371 | 11,011,247 | 143,146,211 |
| -1 | -13 | -41 | -73 | -169 | -283 | -533 | -949 | -2,993 | -3,679 | -6,929 | -11,603 | -12,337 | -20,659 | -38,909 | -47,827 | -150,839 | -268,567 | -505,817 | -847,019 | -1,960,907 | -3,491,371 | -11,011,247 | -143,146,211 |
