Question

find the hcf of a least composite number and least t
wo digit prime number​

Answer 1

Answer:

1

since the only didgit divisible by least composite number 2 and least two digit prime number 11 is 1

Answer 2

Step-by-step explanation:

Given :-

Least Composite number and least two digit prime number .

To find :-

Find their HCF?

Solution :-

We know that

The least composite number = 4

The least two digit prime number = 11

Their HCF = HCF (4,11)

4 = 1×4

4 = 2×2

4 = 4×1

Factors of 4 = 1,2,4

and

11 = 1×11

11 = 11×1

Factors of 11 = 1,11

Common factors of 4 and 11 = 1

The Greatest Common factor of 4 and 11 = 1

HCF (4,11) = 1

Answer:-

The HCF of the Least Composite number and least two digit prime number = 1

Used formulae:-

• HCF = Heighest Common Factor
• HCF is also called as GCF or GCD
• Factor is also called Divisor
• HCF is the heighest common factor of two or more numbers
• The HCF of two numbers is 1 the numbers are called Co-primes or Relatively primes.
• The number having two factors 1 and itself are called prime numbers.
• Ex:2,3,5,7,9,11,13,17,19,..
• The numbers other than primes or the numbers having three or more than three factors are called Composite numbers.
• EX:- 4,6,8,9,10,...
