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 140,124,769, 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 | 140,124,769 | |
-1 | -140,124,769 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,124,769.
Example:
1 x 140,124,769 = 140,124,769
and
-1 x -140,124,769 = 140,124,769
Notice both answers equal 140,124,769
With that explanation out of the way, let's continue. Next, we take the number 140,124,769 and divide it by 2:
140,124,769 ÷ 2 = 70,062,384.5
If the quotient is a whole number, then 2 and 70,062,384.5 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 | 140,124,769 | |
-1 | -140,124,769 |
Now, we try dividing 140,124,769 by 3:
140,124,769 ÷ 3 = 46,708,256.3333
If the quotient is a whole number, then 3 and 46,708,256.3333 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 | 140,124,769 | |
-1 | -140,124,769 |
Let's try dividing by 4:
140,124,769 ÷ 4 = 35,031,192.25
If the quotient is a whole number, then 4 and 35,031,192.25 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 | 140,124,769 | |
-1 | 140,124,769 |
If you did it right, you will end up with this table:
1 | 2,029 | 69,061 | 140,124,769 |
-1 | -2,029 | -69,061 | -140,124,769 |
