Therefore, GCD of numbers 234, 510, 21, 151 is 1

Given Input Data is 234, 510, 21, 151

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

Prime Factorization of 234 is 2 x 3 x 3 x 13

Prime Factorization of 510 is 2 x 3 x 5 x 17

Prime Factorization of 21 is 3 x 7

Prime Factorization of 151 is 151

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(234, 510) = 19890

GCD(234, 510) = ( 234 x 510 ) / 19890

GCD(234, 510) = 119340 / 19890

GCD(234, 510) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 21

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

LCM(6, 21) = 42

GCD(6, 21) = ( 6 x 21 ) / 42

GCD(6, 21) = 126 / 42

GCD(6, 21) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 151

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

LCM(3, 151) = 453

GCD(3, 151) = ( 3 x 151 ) / 453

GCD(3, 151) = 453 / 453

GCD(3, 151) = 1

GCD of 234, 510, 21, 151 is 1
