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 140,044,975, 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 | 140,044,975 | |
| -1 | -140,044,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,044,975.
Example:
1 x 140,044,975 = 140,044,975
and
-1 x -140,044,975 = 140,044,975
Notice both answers equal 140,044,975
With that explanation out of the way, let's continue. Next, we take the number 140,044,975 and divide it by 2:
140,044,975 ÷ 2 = 70,022,487.5
If the quotient is a whole number, then 2 and 70,022,487.5 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 | 140,044,975 | |
| -1 | -140,044,975 |
Now, we try dividing 140,044,975 by 3:
140,044,975 ÷ 3 = 46,681,658.3333
If the quotient is a whole number, then 3 and 46,681,658.3333 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 | 140,044,975 | |
| -1 | -140,044,975 |
Let's try dividing by 4:
140,044,975 ÷ 4 = 35,011,243.75
If the quotient is a whole number, then 4 and 35,011,243.75 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 | 140,044,975 | |
| -1 | 140,044,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 349 | 1,745 | 2,293 | 2,443 | 8,725 | 11,465 | 12,215 | 16,051 | 57,325 | 61,075 | 80,255 | 401,275 | 800,257 | 4,001,285 | 5,601,799 | 20,006,425 | 28,008,995 | 140,044,975 |
| -1 | -5 | -7 | -25 | -35 | -175 | -349 | -1,745 | -2,293 | -2,443 | -8,725 | -11,465 | -12,215 | -16,051 | -57,325 | -61,075 | -80,255 | -401,275 | -800,257 | -4,001,285 | -5,601,799 | -20,006,425 | -28,008,995 | -140,044,975 |
