Therefore, GCD of numbers 155, 330, 78, 937 is 1

Given Input Data is 155, 330, 78, 937

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

Prime Factorization of 155 is 5 x 31

Prime Factorization of 330 is 2 x 3 x 5 x 11

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 937 is 937

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(155, 330) = 10230

GCD(155, 330) = ( 155 x 330 ) / 10230

GCD(155, 330) = 51150 / 10230

GCD(155, 330) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 78

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

LCM(5, 78) = 390

GCD(5, 78) = ( 5 x 78 ) / 390

GCD(5, 78) = 390 / 390

GCD(5, 78) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 937

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

LCM(1, 937) = 937

GCD(1, 937) = ( 1 x 937 ) / 937

GCD(1, 937) = 937 / 937

GCD(1, 937) = 1

GCD of 155, 330, 78, 937 is 1
