Given Input Data is 551, 380, 69, 750

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

Prime Factorization of 551 is 19 x 29

Prime Factorization of 380 is 2 x 2 x 5 x 19

Prime Factorization of 69 is 3 x 23

Prime Factorization of 750 is 2 x 3 x 5 x 5 x 5

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(551, 380) = 11020

GCD(551, 380) = ( 551 x 380 ) / 11020

GCD(551, 380) = 209380 / 11020

GCD(551, 380) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 69

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

LCM(19, 69) = 1311

GCD(19, 69) = ( 19 x 69 ) / 1311

GCD(19, 69) = 1311 / 1311

GCD(19, 69) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 750

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

LCM(1, 750) = 750

GCD(1, 750) = ( 1 x 750 ) / 750

GCD(1, 750) = 750 / 750

GCD(1, 750) = 1

GCD of 551, 380, 69, 750 is 1
