A Factor Is A Number That Divides Into Another Number Exactly. E.g. The Factors Of 12 Are 1, 2, 3, 4, 6 And 12.
If You Were Trying To Find The Highest Common Factor You Write Out The Factors Of All Numbers. E.g. 20 And 30.
Factors Of 20: 1, 2, 4, 5, 10 And 20.
Factors Of 30: 1, 2, 3, 5, 6, 10, 15 And 30.
So The Highest Common Factor Of 20 And 30 Is 10 Because It Is The Highest Factor That Appears In Both Factor Lists.
It Is The Same For The LCM Except You Write Out The Multiples Of The numbers Instead. E.g. 5 And 6.
Multiples Of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, And 50.
Multiples Of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54 And 60.
So The Lowest Common Multiple Is 30. It Appears In Both Lists And Is The Lowest.
An easy way to find the HCF of a pair of numbers is listing out the prime factors. A way to do that is to use a factor tree. Find the common prime factors and multiply them together. e.g. if the prime factors were (2,2,3,3,3,5) and (2,3,3,5,5,7) then you would multiply 2,3,3 and 5.

What is he difference between hcf and LCM of two numbers?
The greatest common factor, or GCF, (also known as HCF) is the largest positive integer that will divide evenly with no remainder into all the members of a given set of numbers. The least common multiple, or LCM, is the smallest positive integer that all the members of a given set of numbers will divide into evenly with no remainder. Factors go into numbers, numbers go into multiples.
Find the LCM for the following set of numbers.8 9 36?
The LCM is 72.
Find the LCM of this set of numbers 9 8?
The Least Common Multiple (LCM) for 9 8 is 72.
What is the LCM for set of numbers 315 30?
The LCM is: 630
What is the LCM of this set of numbers 1198 and 22?
The LCM is: 13,178
What is HCF and LCM of 70?
You need at least two numbers to find either of those.
How do you find the least common multiple that are prime?
The LCM of a set of prime numbers is their product.

Find the LCM for the following set of numbers.8 9 36?
The LCM is 72.
How do you find HCF of a set of numbers?
List the factors of each of the numbers in the set. Write down the numbers that appear on all the lists. Choose the largest one.
What are the properties of HCF?
The HCF of a set of numbers divides evenly into each member of the set and it is the largest number for which that is true.
How are gcf LCM and prime factorization related?
You can find the GCF and/or the LCM of a set of numbers by comparing the prime factorizations of the individual members of the set.
Find the LCM of this set of numbers 9 8?
The Least Common Multiple (LCM) for 9 8 is 72.
What are the prime factor of HCF?
Each HCF has its own set of prime factors.
How Can the LCM of a set of numbers can ever be smaller than the other numbers?
The LCM of a set of numbers can never be smaller than the largest number in the set.
How can you find the LCM of a set of a numbers given their greatest common factor without listing the multiples of the numbers?
If you have two numbers, multiply them together and divide that total by the GCF. The result will be the LCM.
How can you find the GCF of a given set of numbers given their LCM but without listing the factors of the numbers?
By finding their common prime numbers.
