Quick Answer: How Do You Calculate The LCM?

What is the LCM for 15 and 10?

Least common multiple (LCM) of 10 and 15 is 30..

What is the LCM of 3 and 4?

The smallest common multiple of two or more numbers is called their Least Common Multiple (LCM). The LCM of 3 and 4 is 12.

What is the LCM for 24 and 36?

Explanation: The LCM of 24 and 36 is the smallest positive integer that divides the numbers 24 and 36 without a remainder. If you just want to know what is the least common multiple of 24 and 36, it is 72. Usually, this is written as.

What is the GCF of 4 and 30?

2Greatest common factor (GCF) of 4 and 30 is 2.

How do you find the LCM using the list?

Find the least common multiple (LCM) of two numbers by listing multiplesList 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 the LCM for 4?

Multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, 36, … Multiples of 6 are: 6, 12, 18, 24, 30, 36, … Multiples of 8 are: 8, 16, 24, 32, 40, …. So 24 is the least common multiple (I can’t find a smaller one!)

What is the HCF of 18 and 24?

We found the factors and prime factorization of 18 and 24. The biggest common factor number is the GCF number. So the greatest common factor 18 and 24 is 6.

What is the LCM of 8 and 6?

Multiples of 8 are: 8, 16, 24, 32, 40, etc. The LCM for 6 and 8 = 24 because this is the first multiple they have in common.

What is the LCM of 12 and 15?

LCM Example 60 is a common multiple (a multiple of both 12 and 15), and there are no lower common multiples. Therefore, the lowest common multiple of 12 and 15 is 60.

What is the LCM of 30 and 45?

Least common multiple (LCM) of 30 and 45 is 90.

What is the HCF of 4 and 8?

Greatest common factor (GCF) of 4 and 8 is 4. We will now calculate the prime factors of 4 and 8, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 4 and 8.

What is the LCM of 15 and 20?

Least common multiple (LCM) of 15 and 20 is 60.

What is the LCM of 2 and 4?

Explanation: Multiples of 2 are {2,4,6,8,10,12,14,16,…} Multiples of 4 are {4,8,12,16,…….) Hence common multiples are {4,8,12,16,…} and Lowest Common Multiple is 4 .

What is the LCM of 5 and 11?

Least common multiple (LCM) of 5 and 11 is 55.

What is the LCM of 8 and 12?

The first multiple that 8 and 12 have in common is 24. Notice that 48 is also a common multiple; however, 24 is the smallest number that they have in common. This makes it the least common multiple.
