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 83,870,305, 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 | 83,870,305 | |
| -1 | -83,870,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,870,305.
Example:
1 x 83,870,305 = 83,870,305
and
-1 x -83,870,305 = 83,870,305
Notice both answers equal 83,870,305
With that explanation out of the way, let's continue. Next, we take the number 83,870,305 and divide it by 2:
83,870,305 ÷ 2 = 41,935,152.5
If the quotient is a whole number, then 2 and 41,935,152.5 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 | 83,870,305 | |
| -1 | -83,870,305 |
Now, we try dividing 83,870,305 by 3:
83,870,305 ÷ 3 = 27,956,768.3333
If the quotient is a whole number, then 3 and 27,956,768.3333 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 | 83,870,305 | |
| -1 | -83,870,305 |
Let's try dividing by 4:
83,870,305 ÷ 4 = 20,967,576.25
If the quotient is a whole number, then 4 and 20,967,576.25 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 | 83,870,305 | |
| -1 | 83,870,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 37 | 115 | 185 | 529 | 851 | 857 | 2,645 | 4,255 | 4,285 | 19,573 | 19,711 | 31,709 | 97,865 | 98,555 | 158,545 | 453,353 | 729,307 | 2,266,765 | 3,646,535 | 16,774,061 | 83,870,305 |
| -1 | -5 | -23 | -37 | -115 | -185 | -529 | -851 | -857 | -2,645 | -4,255 | -4,285 | -19,573 | -19,711 | -31,709 | -97,865 | -98,555 | -158,545 | -453,353 | -729,307 | -2,266,765 | -3,646,535 | -16,774,061 | -83,870,305 |
