What is the fastest way to find the LCM of a fraction?
5/12 + 3/20
- 1st) State the challenge.
- 2nd) Make a proper fraction out of the two denominators.
- 3rd) Simplify that fraction to lowest terms and then flip it (get its ‘reciprocal.
- 4th) Multiply the original fraction by the reciprocal (the flipped fraction).
- 5th) You just found the LCD.
What is the formula of LCM of fraction?
The Least Common Multiple (LCM) of two integers a and b, usually denoted by LCM (a, b), is the smallest positive integer that is divisible by both a and b….Formula of L.C.M.

How do you find the LCM of a mixed fraction?
Step 1: Find the Lowest Common Multiple (LCM) between the denominators. Step 2: Multiply the numerator and denominator of each fraction by a number so that they have the LCM as their new denominator. Step 3: Add or subtract the numerators and keep the denominator the same.
How do you find the LCM answer?
How to Find LCM by Listing Multiples
- List the multiples of each number until at least one of the multiples appears on all lists.
- Find the smallest number that is on all of the lists.
- This number is the LCM.
How to find the HCF and lcm of two numbers?
Both HCF and LCM of given numbers can be found by using two methods; they are division method and prime factorization. The product of LCM and HCF of any two given natural numbers is equivalent to the product of the given numbers. Suppose A and B are two numbers, then. Example: If 3 and 8 are two numbers. Hence, proved.
What is the HCF of 12 and 15?
For example, the HCF of 12 and 15 is 3. Because 3 is the only common factor for both the numbers 12 and 15 and it is the largest number that divides both the numbers. The followings are the relation between HCF and LCM. Go through the relation between HCF and LCM, solve the problem using the relations in an easy way.
What is the LCM of two prime numbers?
The LCM of two or more prime numbers is nothing but their product. The product of two numbers, a and b, is equal to the product of their HCF and LCM. It is also known as LCM and HCF formula, which we discussed above.
What is the LCM of 10 15 and 20?
For example, LCM of 10, 15, and 20 is 60. Highest Common Factor (HCF): The largest or greatest factor common to any two or more given natural numbers is termed as HCF of given numbers. Also known as GCD (Greatest Common Divisor).
