Therefore, GCD of numbers 430, 246, 77 is 1

Given Input Data is 430, 246, 77

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

Prime Factorization of 430 is 2 x 5 x 43

Prime Factorization of 246 is 2 x 3 x 41

Prime Factorization of 77 is 7 x 11

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(430, 246) = 52890

GCD(430, 246) = ( 430 x 246 ) / 52890

GCD(430, 246) = 105780 / 52890

GCD(430, 246) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 77

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

LCM(2, 77) = 154

GCD(2, 77) = ( 2 x 77 ) / 154

GCD(2, 77) = 154 / 154

GCD(2, 77) = 1

GCD of 430, 246, 77 is 1
