Therefore, GCD of numbers 531, 549, 29, 615 is 1

Given Input Data is 531, 549, 29, 615

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

Prime Factorization of 531 is 3 x 3 x 59

Prime Factorization of 549 is 3 x 3 x 61

Prime Factorization of 29 is 29

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(531, 549) = 32391

GCD(531, 549) = ( 531 x 549 ) / 32391

GCD(531, 549) = 291519 / 32391

GCD(531, 549) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 29

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

LCM(9, 29) = 261

GCD(9, 29) = ( 9 x 29 ) / 261

GCD(9, 29) = 261 / 261

GCD(9, 29) = 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 531, 549, 29, 615 is 1
