Therefore, GCD of numbers 91, 169, 875, 745 is 1

Given Input Data is 91, 169, 875, 745

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

Prime Factorization of 91 is 7 x 13

Prime Factorization of 169 is 13 x 13

Prime Factorization of 875 is 5 x 5 x 5 x 7

Prime Factorization of 745 is 5 x 149

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(91, 169) = 1183

GCD(91, 169) = ( 91 x 169 ) / 1183

GCD(91, 169) = 15379 / 1183

GCD(91, 169) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 875

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

LCM(13, 875) = 11375

GCD(13, 875) = ( 13 x 875 ) / 11375

GCD(13, 875) = 11375 / 11375

GCD(13, 875) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 745

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

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

GCD(1, 745) = 745 / 745

GCD(1, 745) = 1

GCD of 91, 169, 875, 745 is 1
