How do you find the LCM of two numbers?
The product of HCF of two numbers and the LCM of two numbers is equal to the product of two numbers. Therefore, the formula to find LCM of two numbers is, LCM of two numbers = product of two numbers ÷ HCF of two numbers.

How do you find the GCF of two numbers?
To find the greatest common factor (GCF) between numbers, take each number and write it’s prime factorization. Then, identify the factors common to each number and multiply those common factors together.
What is the easiest way to find the LCM?

What is the LCM of 2 and 2? Answer: LCM of 2 and 2 is 2.
How do you solve GCF problems?
Here’s how to find the GCF of a set of numbers using prime factorization:
- List the prime factors of each number.
- Circle every common prime factor — that is, every prime factor that’s a factor of every number in the set.
- Multiply all the circled numbers. The result is the GCF.

Youtube quote: And 63 7 can be divided into 42 6 equal times and 7 can be divided into 63 9 equal times. Now we have to check to see if 7 is our greatest common factor or only a common factor.
What is GCF and LCM in math?
The greatest common factor (GCF) is the largest number that is a factor of two or more numbers, and the least common multiple (LCM) is the smallest number that is a multiple of two or more numbers.
