Therefore, GCD of numbers 636, 212, 62, 155 is 1

Given Input Data is 636, 212, 62, 155

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

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 212 is 2 x 2 x 53

Prime Factorization of 62 is 2 x 31

Prime Factorization of 155 is 5 x 31

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(636, 212) = 636

GCD(636, 212) = ( 636 x 212 ) / 636

GCD(636, 212) = 134832 / 636

GCD(636, 212) = 212

Step2:

Here we consider the GCD from the above i.e. 212 as first number and the next as 62

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

LCM(212, 62) = 6572

GCD(212, 62) = ( 212 x 62 ) / 6572

GCD(212, 62) = 13144 / 6572

GCD(212, 62) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 155

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

LCM(2, 155) = 310

GCD(2, 155) = ( 2 x 155 ) / 310

GCD(2, 155) = 310 / 310

GCD(2, 155) = 1

GCD of 636, 212, 62, 155 is 1
