Given Input Data is 530, 550, 489, 429

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

Prime Factorization of 530 is 2 x 5 x 53

Prime Factorization of 550 is 2 x 5 x 5 x 11

Prime Factorization of 489 is 3 x 163

Prime Factorization of 429 is 3 x 11 x 13

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(530, 550) = 29150

GCD(530, 550) = ( 530 x 550 ) / 29150

GCD(530, 550) = 291500 / 29150

GCD(530, 550) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 489

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

LCM(10, 489) = 4890

GCD(10, 489) = ( 10 x 489 ) / 4890

GCD(10, 489) = 4890 / 4890

GCD(10, 489) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 429

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

LCM(1, 429) = 429

GCD(1, 429) = ( 1 x 429 ) / 429

GCD(1, 429) = 429 / 429

GCD(1, 429) = 1

GCD of 530, 550, 489, 429 is 1
