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 63,613,615, 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 | 63,613,615 | |
| -1 | -63,613,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,613,615.
Example:
1 x 63,613,615 = 63,613,615
and
-1 x -63,613,615 = 63,613,615
Notice both answers equal 63,613,615
With that explanation out of the way, let's continue. Next, we take the number 63,613,615 and divide it by 2:
63,613,615 ÷ 2 = 31,806,807.5
If the quotient is a whole number, then 2 and 31,806,807.5 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 | 63,613,615 | |
| -1 | -63,613,615 |
Now, we try dividing 63,613,615 by 3:
63,613,615 ÷ 3 = 21,204,538.3333
If the quotient is a whole number, then 3 and 21,204,538.3333 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 | 63,613,615 | |
| -1 | -63,613,615 |
Let's try dividing by 4:
63,613,615 ÷ 4 = 15,903,403.75
If the quotient is a whole number, then 4 and 15,903,403.75 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 | 63,613,615 | |
| -1 | 63,613,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 361 | 1,235 | 1,805 | 2,711 | 4,693 | 13,555 | 23,465 | 35,243 | 51,509 | 176,215 | 257,545 | 669,617 | 978,671 | 3,348,085 | 4,893,355 | 12,722,723 | 63,613,615 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -361 | -1,235 | -1,805 | -2,711 | -4,693 | -13,555 | -23,465 | -35,243 | -51,509 | -176,215 | -257,545 | -669,617 | -978,671 | -3,348,085 | -4,893,355 | -12,722,723 | -63,613,615 |
