Therefore, GCD of numbers 511, 860, 220, 135 is 1

Given Input Data is 511, 860, 220, 135

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

Prime Factorization of 511 is 7 x 73

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 135 is 3 x 3 x 3 x 5

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(511, 860) = 439460

GCD(511, 860) = ( 511 x 860 ) / 439460

GCD(511, 860) = 439460 / 439460

GCD(511, 860) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 220

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

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

GCD(1, 220) = 220 / 220

GCD(1, 220) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 135

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

LCM(1, 135) = 135

GCD(1, 135) = ( 1 x 135 ) / 135

GCD(1, 135) = 135 / 135

GCD(1, 135) = 1

GCD of 511, 860, 220, 135 is 1
