How do you find GCF and LCM?
To find the GCF and the LCM you have to first at least try to use prime factorization. So use factor trees. Or for the LCM find th least common multiples of the number.
What is the LCM of 100 and 60?
The LCM of 100 and 60 is 300.You can find that is by doing the simplest thing like upside down division of a factor tree. You have to divide with a prime number such as 2,3,5,7,11,13 or a number that cannot be divided by anything but 1 and itself.
Can the HCF of two numbers be a factor of their LCM?
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.

The LCM is 144.
How do you find two numbers if HCF and LCM are known?
The product of the GCF and the LCM of two numbers is equal to the product of the original two numbers. Multiply the GCF and the LCM. The original two numbers will be another factor pair of that total. Find the factor pair that has that GCF and LCM.
When is it useful to find the LCM or Greatest common factor in a problem?
Find the GCF when you want to simplify a fraction. Find an LCM when you want to add and subtract fractions.
