Answer 1

Required Answer :

Kindly refer the attachment for your answer!

Least Common Multiple ( LCM ) :

The smallest number that can divide two or more given numbers without leaving any remainder is called the lowest common multiple. Lowest common multiple is also called the least common multiple and is written as LCM. Always remember that, whenever words like 'least' 'smallest' 'lowest' are used we have to take out the LCM.

Highest Comment Multiple ( HCF ) :

The greatest number that can divide two or more given numbers without leaving any remainder is called the highest common multiple. Highest common multiple is written as HCF. Always remember that, whenever words like 'greatest' 'highest' 'largest' are used we have to take out the HCF.

1. What is a LCM?

Answer:- Least Common multiple

• When two or more numbers have the same numbers as their multiples, those multiplies are said to be common multiples.
• The Least Common multiple (LCM) of two or more numbers is the smallest number that is a multiple of those numbers.

For example:-

1. Find the least common multiple (LCM) of 5 and 10

Step 1:- List the multiple of all given numbers

Step 2:- Identity the common multiples of all given numbers.

Step 3:- Write the least common multiple (LCM) of all given numbers.

Multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40...

Multiples of 10 are 10, 20, 30, 40, 50, 60, 70, 80...

Common multiples of 5 and 10 are 10, 20, 30, 40...

LCM = 10 (the smallest number of the common multiples)

2. What is a HCF?

Answer:- Highest common factor

• If two or more numbers have the same numbers as their factors, those factors are called Common factors.

For example:-

1) Find the HCF of 15 and 25

Step 1:- Find all the factors of the given numbers

Step 2:- Identity the common factors of the given numbers.

Step 3:- The largest of the common factors is the HCF of the given numbers.

Common factors of 15 and 25 → 1, 5

The Highest common factor (HCF) = 5

• The Highest common factor (HCF) is the largest Common factor that two or more numbers have
