Therefore, GCD of numbers 551, 575, 15, 171 is 1

Given Input Data is 551, 575, 15, 171

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

Prime Factorization of 551 is 19 x 29

Prime Factorization of 575 is 5 x 5 x 23

Prime Factorization of 15 is 3 x 5

Prime Factorization of 171 is 3 x 3 x 19

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(551, 575) = 316825

GCD(551, 575) = ( 551 x 575 ) / 316825

GCD(551, 575) = 316825 / 316825

GCD(551, 575) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 171

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

LCM(1, 171) = 171

GCD(1, 171) = ( 1 x 171 ) / 171

GCD(1, 171) = 171 / 171

GCD(1, 171) = 1

GCD of 551, 575, 15, 171 is 1
