Therefore, GCD of numbers 371, 315, 91, 685 is 1

Given Input Data is 371, 315, 91, 685

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

Prime Factorization of 371 is 7 x 53

Prime Factorization of 315 is 3 x 3 x 5 x 7

Prime Factorization of 91 is 7 x 13

Prime Factorization of 685 is 5 x 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(371, 315) = 16695

GCD(371, 315) = ( 371 x 315 ) / 16695

GCD(371, 315) = 116865 / 16695

GCD(371, 315) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 91

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

LCM(7, 91) = 91

GCD(7, 91) = ( 7 x 91 ) / 91

GCD(7, 91) = 637 / 91

GCD(7, 91) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 685

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

LCM(7, 685) = 4795

GCD(7, 685) = ( 7 x 685 ) / 4795

GCD(7, 685) = 4795 / 4795

GCD(7, 685) = 1

GCD of 371, 315, 91, 685 is 1
