Given Input Data is 623, 728, 169

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

Prime Factorization of 623 is 7 x 89

Prime Factorization of 728 is 2 x 2 x 2 x 7 x 13

Prime Factorization of 169 is 13 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(623, 728) = 64792

GCD(623, 728) = ( 623 x 728 ) / 64792

GCD(623, 728) = 453544 / 64792

GCD(623, 728) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 169

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

LCM(7, 169) = 1183

GCD(7, 169) = ( 7 x 169 ) / 1183

GCD(7, 169) = 1183 / 1183

GCD(7, 169) = 1

GCD of 623, 728, 169 is 1
