The lowest common denominator of any two or more whole numbers, such as 4 and 12, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.

20 is the lowest common denominator for 4 and 10.
The easiest way to find a common denominator of two numbers is to multiply them. Therefore, one of the common denominators for 6 and 7 would be 42 (7 x 6). This method will not necessarily produce the lowest common denominator, but it will determine one. For example, multiplying 4 and 6 will give you 24 as a common denominator. However, the lowest common denominator for 4 and 6 is 12.

lcd(4, 6) = 12.
The lowest common denominator of 4/25 and 3/50 is 50.
3/4 = 9/12 so LCD is 12.
20 is the lowest common denominator for 4 and 10.
The LCM is 52
The answer is 120. 30 X 4 = 120. 12 X 10 = 120.
1/4 plus 1/3 is the same as 3/12 plus 4/12 = 7/12To add 1/3 and 1/4, we must establish a common denominator. In this case a common denominator is 4 times 3, or 12. Finding a lowest common denominator is often a good idea but 12 already is the lowest common denominator. We convert both numbers (1/3 and 1/4) to have the common denominator by multiplying each by 1 (one) in the form to achieve the same denominator:1/3 * 4/4 = 4/121/4 * 3/3 = 3/12Now add the number together: 4/12 + 3/12 = 7/12 Since 7/12 can not be reduced, the final answer is 7/12.

Example: 2/3 and 3/4 The LCD of 3 and 4 is 12. Multiply the numerator and the denominator of 2/3 by 4 to make 8/12 Multiply the numerator and the denominator of 3/4 by 3 to make 9/12
