Given Input Data is 516, 255, 155, 755

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

Prime Factorization of 516 is 2 x 2 x 3 x 43

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 155 is 5 x 31

Prime Factorization of 755 is 5 x 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(516, 255) = 43860

GCD(516, 255) = ( 516 x 255 ) / 43860

GCD(516, 255) = 131580 / 43860

GCD(516, 255) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 155

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

LCM(3, 155) = 465

GCD(3, 155) = ( 3 x 155 ) / 465

GCD(3, 155) = 465 / 465

GCD(3, 155) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 755

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

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

GCD(1, 755) = 755 / 755

GCD(1, 755) = 1

GCD of 516, 255, 155, 755 is 1
