Therefore, GCD of numbers 64, 216, 407, 155 is 1

Given Input Data is 64, 216, 407, 155

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

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 216 is 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 407 is 11 x 37

Prime Factorization of 155 is 5 x 31

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(64, 216) = 1728

GCD(64, 216) = ( 64 x 216 ) / 1728

GCD(64, 216) = 13824 / 1728

GCD(64, 216) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 407

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

LCM(8, 407) = 3256

GCD(8, 407) = ( 8 x 407 ) / 3256

GCD(8, 407) = 3256 / 3256

GCD(8, 407) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 155

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

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

GCD(1, 155) = 155 / 155

GCD(1, 155) = 1

GCD of 64, 216, 407, 155 is 1
