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 143,776,675, 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 | 143,776,675 | |
| -1 | -143,776,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,776,675.
Example:
1 x 143,776,675 = 143,776,675
and
-1 x -143,776,675 = 143,776,675
Notice both answers equal 143,776,675
With that explanation out of the way, let's continue. Next, we take the number 143,776,675 and divide it by 2:
143,776,675 ÷ 2 = 71,888,337.5
If the quotient is a whole number, then 2 and 71,888,337.5 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 | 143,776,675 | |
| -1 | -143,776,675 |
Now, we try dividing 143,776,675 by 3:
143,776,675 ÷ 3 = 47,925,558.3333
If the quotient is a whole number, then 3 and 47,925,558.3333 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 | 143,776,675 | |
| -1 | -143,776,675 |
Let's try dividing by 4:
143,776,675 ÷ 4 = 35,944,168.75
If the quotient is a whole number, then 4 and 35,944,168.75 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 | 143,776,675 | |
| -1 | 143,776,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 157 | 175 | 785 | 1,099 | 3,925 | 5,233 | 5,495 | 26,165 | 27,475 | 36,631 | 130,825 | 183,155 | 821,581 | 915,775 | 4,107,905 | 5,751,067 | 20,539,525 | 28,755,335 | 143,776,675 |
| -1 | -5 | -7 | -25 | -35 | -157 | -175 | -785 | -1,099 | -3,925 | -5,233 | -5,495 | -26,165 | -27,475 | -36,631 | -130,825 | -183,155 | -821,581 | -915,775 | -4,107,905 | -5,751,067 | -20,539,525 | -28,755,335 | -143,776,675 |
