Given Input Data is 749, 623, 445, 178

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

Prime Factorization of 749 is 7 x 107

Prime Factorization of 623 is 7 x 89

Prime Factorization of 445 is 5 x 89

Prime Factorization of 178 is 2 x 89

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(749, 623) = 66661

GCD(749, 623) = ( 749 x 623 ) / 66661

GCD(749, 623) = 466627 / 66661

GCD(749, 623) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 445

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

LCM(7, 445) = 3115

GCD(7, 445) = ( 7 x 445 ) / 3115

GCD(7, 445) = 3115 / 3115

GCD(7, 445) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 178

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

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

GCD(1, 178) = 178 / 178

GCD(1, 178) = 1

GCD of 749, 623, 445, 178 is 1
