Therefore, GCD of numbers 619, 243, 66, 408 is 1

Given Input Data is 619, 243, 66, 408

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

Prime Factorization of 619 is 619

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 408 is 2 x 2 x 2 x 3 x 17

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(619, 243) = 150417

GCD(619, 243) = ( 619 x 243 ) / 150417

GCD(619, 243) = 150417 / 150417

GCD(619, 243) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 66

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

LCM(1, 66) = 66

GCD(1, 66) = ( 1 x 66 ) / 66

GCD(1, 66) = 66 / 66

GCD(1, 66) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 408

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

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

GCD(1, 408) = 408 / 408

GCD(1, 408) = 1

GCD of 619, 243, 66, 408 is 1
