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 143,075,275, 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 | 143,075,275 | |
| -1 | -143,075,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,075,275.
Example:
1 x 143,075,275 = 143,075,275
and
-1 x -143,075,275 = 143,075,275
Notice both answers equal 143,075,275
With that explanation out of the way, let's continue. Next, we take the number 143,075,275 and divide it by 2:
143,075,275 ÷ 2 = 71,537,637.5
If the quotient is a whole number, then 2 and 71,537,637.5 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 | 143,075,275 | |
| -1 | -143,075,275 |
Now, we try dividing 143,075,275 by 3:
143,075,275 ÷ 3 = 47,691,758.3333
If the quotient is a whole number, then 3 and 47,691,758.3333 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 | 143,075,275 | |
| -1 | -143,075,275 |
Let's try dividing by 4:
143,075,275 ÷ 4 = 35,768,818.75
If the quotient is a whole number, then 4 and 35,768,818.75 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 | 143,075,275 | |
| -1 | 143,075,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 457 | 1,789 | 2,285 | 3,199 | 8,945 | 11,425 | 12,523 | 15,995 | 44,725 | 62,615 | 79,975 | 313,075 | 817,573 | 4,087,865 | 5,723,011 | 20,439,325 | 28,615,055 | 143,075,275 |
| -1 | -5 | -7 | -25 | -35 | -175 | -457 | -1,789 | -2,285 | -3,199 | -8,945 | -11,425 | -12,523 | -15,995 | -44,725 | -62,615 | -79,975 | -313,075 | -817,573 | -4,087,865 | -5,723,011 | -20,439,325 | -28,615,055 | -143,075,275 |
