Therefore, GCD of numbers 135, 215, 91, 615 is 1

Given Input Data is 135, 215, 91, 615

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

Prime Factorization of 135 is 3 x 3 x 3 x 5

Prime Factorization of 215 is 5 x 43

Prime Factorization of 91 is 7 x 13

Prime Factorization of 615 is 3 x 5 x 41

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(135, 215) = 5805

GCD(135, 215) = ( 135 x 215 ) / 5805

GCD(135, 215) = 29025 / 5805

GCD(135, 215) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 91

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

LCM(5, 91) = 455

GCD(5, 91) = ( 5 x 91 ) / 455

GCD(5, 91) = 455 / 455

GCD(5, 91) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 615

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

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

GCD(1, 615) = 615 / 615

GCD(1, 615) = 1

GCD of 135, 215, 91, 615 is 1
