Therefore, GCD of numbers 641, 574, 161, 869 is 1

Given Input Data is 641, 574, 161, 869

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 641 is 641

Prime Factorization of 574 is 2 x 7 x 41

Prime Factorization of 161 is 7 x 23

Prime Factorization of 869 is 11 x 79

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(641, 574) = 367934

GCD(641, 574) = ( 641 x 574 ) / 367934

GCD(641, 574) = 367934 / 367934

GCD(641, 574) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 161

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

GCD(1, 161) = 161 / 161

GCD(1, 161) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 869

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

GCD(1, 869) = 869 / 869

GCD(1, 869) = 1

GCD of 641, 574, 161, 869 is 1
