What is difference between the HCF and LCM of 10 15 20?

The ratio between hcf and lcm of 10 ,15 ,20 is 1 : 12. List all prime factors for each number. For each prime factor, find where it occurs most often as a factor and write it that many times in a new list. Multiply these factors together to find the LCM.

What is the HCF of 10 15 and 20?

As you can see when you list out the factors of each number, 5 is the greatest number that 10, 15, and 20 divides into.

What is the LCM of 10 15 and 20?

60
Therefore, the LCM of 10, 15 and 20 is 60.

What is the difference between the LCM and HCF of 10?

LCM is the smallest whole number that occurs in both of their time tables and it is the smallest integer that is a multiple of both numbers. Whereas, HCF is the highest common factor between different numbers. It is the largest number that divides two or more than two numbers.

What is the HCF of 10 and 15?

5
Answer: HCF of 10 and 15 is 5.

What is the LCM of 10 and 15?

30
Answer: LCM of 10 and 15 is 30.

What is the difference between LCM and HCF Class 10?

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 does HCF and LCM mean in maths?

In some questions the highest common factor (HCF) or lowest common multiple (LCM) of two large numbers may need to be found.

What is the difference between HCF and LCM?

Difference between HCF and LCM. LCM is the least common multiple and HCF is the highest common factor between different numbers. The main purpose of showing the difference between these two numbers is to show the difference between a factor and a multiple. A multiple of a whole number is an integer that occurs in the time table.

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 12 and 15?

To find the LCM of numbers, first, mention the multiples of each number. Therefore, the multiples of 12 = 12, 24, 36, 48, 60, 72, 84.. etc., The multiples of 15 = 15, 30, 45, 60, 75, 90, 105,.. Etc, The Highest Common Factor ( HCF) is defined as the largest number that divides evenly into all the numbers from a group of numbers.

What is the LCM of 16 and 24?

5, 10, 15, 20, 25, The LCM is 20 because this is the first number that appears in both lists. The HCF of two integers is the largest whole number that divides both numbers without leaving a remainder. For example, the HCF of 16 and 24 is 8.
