Therefore, GCD of numbers 660, 209, 128, 262 is 1

Given Input Data is 660, 209, 128, 262

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 209 is 11 x 19

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 262 is 2 x 131

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, 209) = 12540

GCD(660, 209) = ( 660 x 209 ) / 12540

GCD(660, 209) = 137940 / 12540

GCD(660, 209) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 128

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

LCM(11, 128) = 1408

GCD(11, 128) = ( 11 x 128 ) / 1408

GCD(11, 128) = 1408 / 1408

GCD(11, 128) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 262

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

LCM(1, 262) = 262

GCD(1, 262) = ( 1 x 262 ) / 262

GCD(1, 262) = 262 / 262

GCD(1, 262) = 1

GCD of 660, 209, 128, 262 is 1
