What is the LCD of 3 and 6?
3, 6, 9, 12, 15, 18, 21, The answer is 6, and that is the Least Common Denominator. So let us try using it!
What is the HCF of 10?
To find the HCF of 10 and 15, we will find the prime factorization of the given numbers, i.e. 10 = 2 × 5; 15 = 3 × 5. ⇒ Since 5 is the only common prime factor of 10 and 15. Hence, HCF (10, 15) = 5.
What is the LCM of 4 and 7?

What US the least common multiple of 12 and 9?
Find the prime factorization of 9 9 = 3 x 3
What are the common multiples of 9 and 12?
Common multiples of 9 and 12 are numbers that both 9 and 12 can be divided into evenly with no remainder . To find the common multiples of 9 and 12, we compare the list of multiples of 9 with the list of multiples of 12 to see what they have in common. To create a list of multiples of 9, we multiply 9 by 1, 9 by 2, and so on like this: 9 x 1 = 9. 9 x 2 = 18.
How do you calculate the least common denominator?
To find the least common denominator, simply list the multiples of each denominator (multiply by 2, 3, 4, etc. out to about 6 or seven usually works) then look for the smallest number that appears in each list. Example: Suppose we wanted to add 1/5 + 1/6 + 1/15.
How do you find the LCD of a fraction?
To find the LCD of the fractions, we find the least common multiple (LCM) of their denominators. LCD can be found by two methods. In the first method, LCD of two or more fractions is found as the smallest of all the possible common denominators.In second method, we find the prime factors of the denominators.
