How do u find the LCM?
Find the least common multiple (LCM) of two numbers by listing multiples
- List the first several multiples of each number.
- Look for multiples common to both lists.
- Look for the smallest number that is common to both lists.
- This number is the LCM.
What is an example of LCM?
LCM denotes the least common factor or multiple of any two or more given integers. For example, L.C.M of 16 and 20 will be 2 x 2 x 2 x 2 x 5 = 80, where 80 is the smallest common multiple for numbers 16 and 20.
What is HCF and LCM?
The H.C.F. defines the greatest factor present in between given two or more numbers, whereas L.C.M. defines the least number which is exactly divisible by two or more numbers. H.C.F. is also called the greatest common factor (GCF) and LCM is also called the Least Common Divisor.
What is LCM and GCF?
The greatest common factor (GCF) is the largest number that is a factor of two or more numbers, and the least common multiple (LCM) is the smallest number that is a multiple of two or more numbers.
Why LCM is used in real life?
This problem can be solved using Least Common Multiple because we are trying to figure out when the soonest (Least) time will be that as the event of exercising continues (Multiple), it will occur at the same time (Common). Answer : L.C.M. of 12 and 8 is 24 . SO, They will exercise together again in 24 days.
What is LCM and GCD with example?
The least common multiple (LCM) of two integers is the smallest positive integer that is a multiple of both. The greatest common divisor (GCD) of two integers is the largest positive integer dividing both. The product of the two numbers is the product of the LCM and the GCD.
What is the LCM of 30 and 36?
180
Answer: LCM of 30 and 36 is 180.
Who discovered LCM?
mathematician Euclid
… algorithm, procedure for finding the greatest common divisor (GCD) of two numbers, described by the Greek mathematician Euclid in his Elements (c. 300 bc). The method is computationally efficient and, with minor modifications, is still used by computers.
Who invented LCM and HCF?
Euclid discovered the method for finding the HCF.
How do you find HCF and LCM?
LCM and HCF Relation
Suppose P and Q are two numbers, then. Relation 2: As HCF of co-prime numbers is 1. Therefore we get LCM of given co-prime numbers is equal to the product of the numbers. LCM of Co-prime Numbers = Product of The co-prime Numbers.
What is the LCM of 24 and 36?
72
The LCM of 24 and 36 is 72. To find the least common multiple of 24 and 36, we need to find the multiples of 24 and 36 (multiples of 24 = 24, 48, 72, 96; multiples of 36 = 36, 72, 108, 144) and choose the smallest multiple that is exactly divisible by 24 and 36, i.e., 72.
What is the LCM of 40?
To find the LCM of 40 and 50 using prime factorization, we will find the prime factors, (40 = 2 × 2 × 2 × 5) and (50 = 2 × 5 × 5). LCM of 40 and 50 is the product of prime factors raised to their respective highest exponent among the numbers 40 and 50. ⇒ LCM of 40, 50 = 23 × 52 = 200.
What is the LCM of 54 and 72?
Answer: LCM of 54 and 72 is 216.
What is the LCM of 60?
The LCM of 60 and 60 is 60.
What is the difference between LCD and LCM?
The only difference between LCD and LCM is that the LCD is the LCM in the denominator of a fraction. So, one could say that least common denominators are a special case of least common multiples.
