Given Input Data is 623, 693, 98, 478

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

Prime Factorization of 623 is 7 x 89

Prime Factorization of 693 is 3 x 3 x 7 x 11

Prime Factorization of 98 is 2 x 7 x 7

Prime Factorization of 478 is 2 x 239

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(623, 693) = 61677

GCD(623, 693) = ( 623 x 693 ) / 61677

GCD(623, 693) = 431739 / 61677

GCD(623, 693) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 98

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

LCM(7, 98) = 98

GCD(7, 98) = ( 7 x 98 ) / 98

GCD(7, 98) = 686 / 98

GCD(7, 98) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 478

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

LCM(7, 478) = 3346

GCD(7, 478) = ( 7 x 478 ) / 3346

GCD(7, 478) = 3346 / 3346

GCD(7, 478) = 1

GCD of 623, 693, 98, 478 is 1
