Therefore, GCD of numbers 394, 434, 615, 740 is 1

Given Input Data is 394, 434, 615, 740

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

Prime Factorization of 394 is 2 x 197

Prime Factorization of 434 is 2 x 7 x 31

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 740 is 2 x 2 x 5 x 37

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(394, 434) = 85498

GCD(394, 434) = ( 394 x 434 ) / 85498

GCD(394, 434) = 170996 / 85498

GCD(394, 434) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 615

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

LCM(2, 615) = 1230

GCD(2, 615) = ( 2 x 615 ) / 1230

GCD(2, 615) = 1230 / 1230

GCD(2, 615) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 740

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

LCM(1, 740) = 740

GCD(1, 740) = ( 1 x 740 ) / 740

GCD(1, 740) = 740 / 740

GCD(1, 740) = 1

GCD of 394, 434, 615, 740 is 1
