Therefore, GCD of numbers 355, 215, 650, 137 is 1

Given Input Data is 355, 215, 650, 137

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

Prime Factorization of 355 is 5 x 71

Prime Factorization of 215 is 5 x 43

Prime Factorization of 650 is 2 x 5 x 5 x 13

Prime Factorization of 137 is 137

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(355, 215) = 15265

GCD(355, 215) = ( 355 x 215 ) / 15265

GCD(355, 215) = 76325 / 15265

GCD(355, 215) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 650

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

LCM(5, 650) = 650

GCD(5, 650) = ( 5 x 650 ) / 650

GCD(5, 650) = 3250 / 650

GCD(5, 650) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 137

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

LCM(5, 137) = 685

GCD(5, 137) = ( 5 x 137 ) / 685

GCD(5, 137) = 685 / 685

GCD(5, 137) = 1

GCD of 355, 215, 650, 137 is 1
