Each place value column in a binary number can have only one of two values: 0 or 1; thus the counting numbers in binary are:
1, 10, 11, 100, 101, 110, 111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111, 10000, 10001, 10010, ...
To product (or multiply) binary numbers, use long multiplication like normal, but when adding the columns together remember how binary counting goes (above) which means you may carry more than 1, in which case carry to more than one column, eg if the sum is 101 put a 1 under the column, carry 10 to the previous 2 columns (ie 0 to the next left column and 1 to the column to the left of that one).
example 1111 × 101 = 1001011 (in decimal 15 × 5 = 75)

If you meant to produce binary numbers, that is convert decimal to binary, then the general algorithm to convert between bases works:
For binary, the new base is 2.
Example 75 in binary:
75 ÷ 2 = 37 r 1
37 ÷ 2 = 18 r 1
18 ÷ 2 = 9 r 0
9 ÷ 2 = 4 r 1
4 ÷ 2 = 2 r 0
2 ÷ 2 = 1 r 0
1 ÷ 2 = 0 r 1
→ 75 in binary is 1001011
To convert from binary to decimal remember that each place value column of a binary number has twice the value of the column to its right; add the value of each column by its binary digit (bit).
eg 1001011 = (1 × 64) + (0 × 32) + (0 × 16) + (1 × 8) + (0 × 4) + (1 × 2) + (1 × 1) = 64 + 8 + 2 + 1 = 75
It may be easier to start from the right hand end of the number and work left as then you start with the place column value of 1 and multiply it by 2 each time:
eg 1001011 = (1 × 1) + (1 × 2) + (0 × 4) + (1 × 8) + (0 × 16) +( 0 × 32) + (1 × 64) = 1 + 2 + 8 + 64 = 75

A product is a binary operation: you need 2 (or more) numbers in order for there to be a product.
A product is a binary operator. That means a product is the result of combining TWO numbers. You cannot have a product of just one number - whether it is a fraction or not is irrelevant.
"Product" is a binary operation. That means you need two numbers before you can have a product. So 34 does not have a product and so there is no way to find it!
The only numbers used in binary are 0 and 1
