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 142,574,075, 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 | 142,574,075 | |
| -1 | -142,574,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,574,075.
Example:
1 x 142,574,075 = 142,574,075
and
-1 x -142,574,075 = 142,574,075
Notice both answers equal 142,574,075
With that explanation out of the way, let's continue. Next, we take the number 142,574,075 and divide it by 2:
142,574,075 ÷ 2 = 71,287,037.5
If the quotient is a whole number, then 2 and 71,287,037.5 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 | 142,574,075 | |
| -1 | -142,574,075 |
Now, we try dividing 142,574,075 by 3:
142,574,075 ÷ 3 = 47,524,691.6667
If the quotient is a whole number, then 3 and 47,524,691.6667 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 | 142,574,075 | |
| -1 | -142,574,075 |
Let's try dividing by 4:
142,574,075 ÷ 4 = 35,643,518.75
If the quotient is a whole number, then 4 and 35,643,518.75 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 | 142,574,075 | |
| -1 | 142,574,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 116,387 | 581,935 | 814,709 | 2,909,675 | 4,073,545 | 5,702,963 | 20,367,725 | 28,514,815 | 142,574,075 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -116,387 | -581,935 | -814,709 | -2,909,675 | -4,073,545 | -5,702,963 | -20,367,725 | -28,514,815 | -142,574,075 |
