What is the least common multiple LCM of 4 and 8?
8
Answer: LCM of 4 and 8 is 8.
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’s the LCM of 4 and 4?
4
What is the LCM of 4 and 4? Answer: LCM of 4 and 4 is 4.
What is the greatest common factor of 4 and 8?
The GCF of 4 and 8 is 4. To calculate the greatest common factor of 4 and 8, we need to factor each number (factors of 4 = 1, 2, 4; factors of 8 = 1, 2, 4, 8) and choose the greatest factor that exactly divides both 4 and 8, i.e., 4.
What is the LCM of 8 and 3?
24
So the lowest common multiple of 3 and 8 is 24.
How do you calculate HCF and LCM?
To find the HCF, find any prime factors that are in common between the products. Each product contains two 2s and one 3, so use these for the HCF. To find the LCM, multiply the HCF by all the numbers in the products that have not yet been used.
What does LCM mean in math?
least common multiple
Definition of least common multiple 1 : the smallest common multiple of two or more numbers.
How do you find the LCM of a Venn diagram?
Once we have the Venn diagram, finding the LCM is simply a matter of multiplying all the numbers in the Venn diagram together: It is important to note that when you have two numbers, and are asked to find the HCF and LCM, the LCM will be the larger of the two numbers.
How do you find the LCM and HCF of a number?
Sometimes you are given numbers expressed as a product of prime factors. For example, 8 = 23 and 90 = 2 × 32 × 5. If you want to find the LCM and HCF in an exam, we can use prime factor form to simplify the process.
How to find LCM using exponents?
How to find LCM by Prime Factorization using Exponents 1 Find all the prime factors of each given number and write them in exponent form. 2 List all the prime numbers found, using the highest exponent found for each. 3 Multiply the list of prime factors with exponents together to find the LCM.
What is the value of LCM 24 300?
Therefore LCM (12,30) = 60. Using all prime numbers found as often as each occurs most often we take 2 × 2 × 2 × 3 × 5 × 5 = 600 Therefore LCM (24,300) = 600. Find all the prime factors of each given number and write them in exponent form.
