Therefore, GCD of numbers 77, 784, 466, 520 is 1

Given Input Data is 77, 784, 466, 520

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

Prime Factorization of 77 is 7 x 11

Prime Factorization of 784 is 2 x 2 x 2 x 2 x 7 x 7

Prime Factorization of 466 is 2 x 233

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

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(77, 784) = 8624

GCD(77, 784) = ( 77 x 784 ) / 8624

GCD(77, 784) = 60368 / 8624

GCD(77, 784) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 466

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

LCM(7, 466) = 3262

GCD(7, 466) = ( 7 x 466 ) / 3262

GCD(7, 466) = 3262 / 3262

GCD(7, 466) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 520

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

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

GCD(1, 520) = 520 / 520

GCD(1, 520) = 1

GCD of 77, 784, 466, 520 is 1
