Given Input Data is 660, 579, 155, 956

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

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 579 is 3 x 193

Prime Factorization of 155 is 5 x 31

Prime Factorization of 956 is 2 x 2 x 239

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(660, 579) = 127380

GCD(660, 579) = ( 660 x 579 ) / 127380

GCD(660, 579) = 382140 / 127380

GCD(660, 579) = 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 956

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

LCM(1, 956) = 956

GCD(1, 956) = ( 1 x 956 ) / 956

GCD(1, 956) = 956 / 956

GCD(1, 956) = 1

GCD of 660, 579, 155, 956 is 1
